再生LCP液晶聚合物：精密电子件的水口料，量小但身价高

LCP在塑料圈里是个“小众贵族”——用量不大，身价不低。别的塑料按吨卖，它按公斤论价，一公斤新料顶别人好几公斤。可越是这样的料，车间里切下来的水口料越心疼。今天这篇，就把LCP这门小生意讲明白：它凭什么这么金贵、水口料回收到底值不值、市场流通量小这件事对你选材意味着什么。

先把LCP是啥说清楚。LCP是液晶聚合物的简称，英文Liquid Crystal Polymer。它加热熔融时能像液体一样流动、充进精密模具，一冷却又保持取向，又刚又薄又耐高温。手机里的高速连接器、5G基站的射频件、FPC柔性电路板，都离不开它。为啥？因为它的介质损耗极低，高频信号跑上去衰减小；耐热又好，扛得住SMT回流焊那一两百摄氏度的折腾。这俩本事，别的塑料很难同时做到。宁波市科隆新材料有限公司做塑料原料供应，工贸一体，常见再生塑料品类常年备货；LCP这类小众特种料，量小、门路窄，得专门去淘。

得先说清楚一个大前提：再生LCP市场流通量小，以特定渠道回收为主。这话不是谦虚，是事实。LCP本来用量就少，又是高端电子件专用，水口料散在各个连接器厂、模组厂里，不像PP那样到处能收。市面上能稳定拿到的再生LCP，多来自特定大厂的干净水口料、特定渠道的改性回用，货源不稳定、批次波动大。所以做LCP选材，别指望像收普通再生料那样随用随买，得提前跟渠道锁料。

5G把LCP推上风口，回收跟着水涨船高

LCP这两年为啥突然热起来？根子在5G和高频通信。以前LCP用得少，是因为普通通信频段用别的料凑合也行。可到了5G、毫米波那一段，信号频率一高，普通塑料介电损耗大、信号传不远还失真，LCP那种低损耗的本事就显得无可替代了。手机里的天线支架、高速连接器，基站里的射频前端、滤波器外壳，都在往LCP上转。行业报告里提到，2024年光是5G基站和智能手机相关组件对LCP薄膜的需求就有好几千吨的量，还在逐年涨。

需求一涨，新料价格就硬，回收的价值也就跟着水涨船高。可回收这步没那么容易走。LCP用量在涨，但分散在无数个连接器厂、模组厂里，单家的水口料量并不大，要把它们一点点收上来、分好类、验好批次，得靠长期扎在这个圈子里的渠道去做。这也是为什么市面上能稳定供货的再生LCP不多——不是没人想收，是料太散、门槛太高。懂行的都明白，这门生意拼的不是价，是你能不能长期拿到干净的一手水口。

还有一点得提醒：别拿再生LCP去比普通再生塑料的价。它贵，不是因为商家想赚黑钱，是因为料本身金贵、回收门槛又高。你要是指望它像回收PP那样便宜一半，那是想多了。它的价值在于——本来就贵的新料，掺一点干净的再生水口，能在不掉关键性能的前提下把成本压下来一截，这就够了。把它当成“有限降本”的工具，而不是“大幅替代”的便宜货，心态就对了。

小众贵族的本事，全在“又薄又稳”

LCP为啥这么金贵？就凭它那几样本事。头一样是薄——它流动性极好，能注出又薄又长的薄壁精密件，手机里那些指甲盖大小的连接器，不薄装不下；第二样是稳——尺寸收缩小、翘曲低，做精密接插件公差才守得住；第三样是耐热，玻纤增强的LCP热变形温度能冲到二百八十摄氏度上下，SMT贴片那道高温工序不怵；第四样，也是它在5G里吃香的原因——介电损耗极低，高频信号传输衰减小，毫米波天线、射频模组都靠它。

说起来LCP再生的难点，还真不少。头一个是它娇贵。LCP反复受热，分子取向和玻纤状态会变，回掺几次后流动性、刚性都跟新料有差距；第二个是怕混，本色水口一掺进黑色料、别的工程塑料，这料的介电和耐热就没法保，只能降级当普通改性料卖，身价一下掉下来；第三个是量碎，单家厂的水口料一个月就那么点，凑不出一车，回收成本被摊高。所以做LCP回收的，都得死磕“干净、单一、可追溯”这六个字。宁可收少一点，也不能把料做脏了——这门小生意，口碑比走量重要。

这里头还有个门道，就是耐热等级。LCP行业里常按E型、S型、T型这么分，耐热一档比一档高。做普通接插件，E型可能够用；要过SMT回流焊，得上S型；那些又高频又高温的件，才轮得到T型。选再生料也是一个道理，别拿着E型的水口去硬顶T型的活，回流焊一烤就变形。所以问再生LCP，先问清楚是哪个耐热等级、玻纤多少，别光看个“LCP”名头就下单——同样是LCP，差一个等级，价钱和用途差着一大截。

正因为身上担着这么多精细活，LCP再生就有个讲究：不能胡来。它跟别的再生料不一样，回掺多了、料脏了，那点宝贵的介电性能和耐热性就往下掉，而这恰恰是客户买它的理由。所以再生LCP做不了大路货，只能在特定要求没那么苛刻的件上掺，或者跟新料按小比例复配。下面这张等级表，就是按玻纤含量和耐热等级分的。

等级	主要来源/形态	关键指标	典型用途
LCP本色水口(30%玻纤)	连接器注塑本色水口	玻纤约30%，本色	高速接插件回掺
LCP 40%玻纤增强	高刚性结构件水口	玻纤约40%，刚性高	结构件、改性回用
LCP E型耐热	中耐热级水口	E型耐热	一般电子接插件
LCP S型耐热	较高耐热级水口	S型耐热	SMT回流焊件
LCP T型耐热	超耐热级水口	T型耐热	高频、高温件
LCP黑色再生改性	黑色水口/回收改性	改性后降级使用	对性能要求不高的件

说明：再生LCP以注塑水口料、改性回用为主，目前市场流通量小、以特定渠道回收为主，等级与物性以厂家官方TDS为准；玻纤含量、耐热E/S/T分级为行业通行划分，具体牌号与介电性能需按检测报告确认。

水口料回收改性，掺一点就省不少

LCP新料贵，一公斤好几十上百块，做精密件的厂，车间里每天切下来的水口、浇道看着不起眼，积少成多就是一笔钱。把这些干净水口收回来、造粒改性，按小比例掺回新料，或者降级用到要求低一点的件上，省的就是实打实的真金白银。

成本项	用全新LCP	掺再生改性LCP	差异说明
原料单价	新料价高	再生水口便宜一截	按掺量摊薄
水口处理	当废料或贱卖	回收造粒改性回用	边角料变宝
掺加比例	——	小比例复配，先试	掺多掉介电/耐热
批次稳定性	稳定	需验批次、对TDS	小众料批次波动大
适用件	高端高频件	中低端或非关键件	关键件慎掺
综合账	成本高	省一截，控风险	会用就划算

结合这笔账，下面的边界清单帮你判断再生LCP该不该掺、掺在哪。

适合掺：对介电、耐热要求不那么苛刻的件，小比例复配新料降本。

别贪量：再生LCP掺多了介电性能、耐热性会掉，关键高频件别赌。

认准来源：只收干净本色水口，别收混色、混料、带油污的杂水口。

锁渠道：流通量小，提前跟固定渠道锁料，别临用到处找货。

先打样：每批再生料先测介电和成型，稳了再上机，别直接大货。

给想试再生LCP的厂提个醒：别一上来就大货。先小批拿样，测三样——介电常数稳不稳、熔融指数跟不跟得上、注塑出来外观和尺寸行不行。这三样过了，再谈掺比例。因为小众料批次本来就飘，你不批批验，到了产线上才发现流动性不对、打不满模，那返工的损失比省下的料钱还多。懂行的厂都是先打样、看数据、再上机，绝不靠经验赌。

连接器厂的水口，专门有人上门收

说个典型情景示例，宁波市科隆新材料有限公司在LCP这类小众料上经手过一些厂，下面按行业常见情形还原。

华南有家做手机高速连接器的厂，用的是三十玻纤的LCP新料，一个月用量不小，车间每天注塑下来的本色水口料堆得不少。以前这些水口要么掺一点回用、要么当杂料便宜处理。老板也知道LCP贵，可一直没把水口当回事——量小、分散，自己没工夫专门分拣。

走投无路之际，他们抱着试试看的心态咨询了科隆新材。科隆新材把话说在前头：再生LCP流通量小、得靠特定渠道，不过你这干净的本色水口，正是别人抢着要的料。给的思路是：把本色水口单独收、不混别的料，造粒后按小比例跟新料复配，先用在对介电要求稍低的非关键件上；关键高频件还是用新料，别拿再生料赌。先打样看介电和成型，稳了再加量。

这家厂后来把LCP水口单独建了个料斗：本色水口不落地、不混别的车间料，攒够一批就通知科隆新材上门收；造粒回来先送样测介电常数和熔融指数，跟新料的曲线对上了才敢上机。头一年量小，慢慢把几个相邻厂的水口也串了起来，凑成稳定的货源。老板说，这跟以前收杂料完全是两码事，得细水长流。宁波市科隆新材料有限公司看重的，正是这种长期、干净、可追溯的小众料货源。

这笔账算下来，老板越算越觉得当初轻看了这堆水口。他给科隆新材算了一笔：以前一公斤水口贱卖才几个钱，现在单独收、改性后掺回，等于把一公斤新料的成本往下拉了一截，一年下来省的料钱够养半个班组。更重要的是，关键件照用新料不冒险，非关键件大胆降本，两头都不耽误。他说，做小料最怕的不是贵，是贵了还买不到、买来了还不稳——这两件事，找对渠道就都解决了。

做下来，这家厂的水口料不再贱卖，掺回产线也省了一截新料钱。老板说，以前觉得LCP量小不值得折腾，现在才明白，正因为它贵、它小众，把干净水口接住才更值钱。做特种料久了有个体会：小众料的回收，赚的不是走量的钱，是把“干净”和“门道”这两样攥在手里的钱。这也是宁波市科隆新材料有限公司收LCP水口时，坚持只收干净本色料、按渠道锁货的原因——量小，就更不能砸了招牌。

再生LCP量小价高，用对地方才划算

再生LCP量小门窄，下面这张场景对照存进手机，选料时翻出来对一对，一条一条对着来，千万别漏掉其中任何一条。千万别贪多，用对地方才是正经。这张表不是让你照单全收，是帮你先排个雷：哪些件能掺、哪些件别碰，心里先有个底，再去找渠道打样，省得来回折腾、耽误了交货期，那才是真不划算的买卖。

说到底，再生LCP这门生意，跟普通再生塑料是两种打法。普通料拼的是量大、价低、走量；它拼的是干净、可追溯、渠道硬。你要是拿着收PP的思路去收LCP，大概率收来一堆掺了杂的杂料，卖不上价还砸手里。反过来，你要是能长期稳住几个大厂的干净水口，这门小生意就是个别人抢不走的饭碗。5G的量还在涨，LCP的需求往后只会多不会少，现在把渠道和口碑攒起来，正是时候。等哪天5G的料遍地都是了，再想切进去，门槛早被人占满了。

应用场景	推荐等级	注意事项	何时别用

LCP is a 'niche aristocrat' in the world of plastics—it’s not used in large quantities, but its value is high. While other plastics are sold by the ton, LCP is priced by the kilogram, and one kilogram of new material is equivalent to several kilograms of others. The more valuable the material, the more painful it is to see sprues cut in the workshop. Today’s article will explain this small LCP business clearly: why it’s so precious, whether it’s worth recycling sprue material, and what the limited market circulation means for your material selection.

First, let's clarify what LCP is. LCP stands for Liquid Crystal Polymer. When it is heated and melted, it can flow like a liquid and fill precise molds; once cooled, it retains orientation, being both stiff and thin, and resistant to high temperatures. High-speed connectors in mobile phones, RF components in 5G base stations, and FPC flexible circuit boards all depend on it. Why? Because it has extremely low dielectric loss, so high-frequency signals experience minimal attenuation; it is also heat-resistant, able to withstand the one or two hundred degrees Celsius of SMT reflow soldering. These two capabilities are hard for other plastics to achieve simultaneously. Ningbo Kolon New Materials Co., Ltd. supplies plastic raw materials, combining production and trade, and keeps common recycled plastics in stock year-round; specialty materials like LCP are low-volume and have limited channels, so you have to specifically seek them out.

First, we need to clarify a major premise: the market circulation of recycled LCP is small, and it is mainly recovered through specific channels. This is not modesty—it is a fact. LCP itself is used in small quantities and is dedicated to high-end electronic components. The leftover material is scattered across various connector and module manufacturers, unlike PP, which can be collected almost anywhere. The recycled LCP that can be steadily obtained on the market mostly comes from clean offcuts of certain large manufacturers or modified reuse from specific channels. The supply is unstable and the batches vary greatly. Therefore, when selecting LCP materials, don’t expect to buy them on demand like ordinary recycled materials; you need to secure the material with the channels in advance.

5G pushes LCP to the forefront, and recycling rises with it.

Why has LCP suddenly become popular in the past two years? The root cause is 5G and high-frequency communication. LCP was used less before because for regular communication bands, other materials could suffice. But when it comes to 5G and millimeter-wave frequencies, as the signal frequency gets higher, ordinary plastics have high dielectric losses, causing signals to not travel far and distort, making LCP's low-loss properties irreplaceable. Antenna brackets and high-speed connectors in smartphones, as well as RF front ends and filter housings in base stations, are all switching to LCP. Industry reports mention that in 2024, just the demand for LCP films from 5G base stations and smartphone-related components will reach several thousand tons, and it is still increasing year by year.

Whenever demand rises, the price of new materials goes up, and the value of recycling rises along with it. But recycling isn't that easy to do. LCP usage is increasing, but it's spread across countless connector manufacturers and module factories. The amount of sprue material from each individual factory isn’t large. Collecting them bit by bit, sorting them properly, and verifying the batches requires channels that have been entrenched in this circle for a long time. This is also why there are not many recycled LCPs on the market that can be supplied stably—not because no one wants to collect them, but because the material is too scattered and the threshold is too high. Those in the know understand that this business isn't about competing on price, but about whether you can consistently get clean, first-hand sprue material over the long term.

One more thing to remind you: don’t compare the price of regenerated LCP with ordinary recycled plastics. It’s expensive not because sellers want to make quick money, but because the material itself is precious and the recycling threshold is high. If you expect it to be half the price like recycled PP, that’s wishful thinking. Its value lies in the fact that—by blending a bit of clean recycled sprue into already expensive virgin material—you can reduce costs somewhat without compromising key performance. That’s enough. Treat it as a tool for 'limited cost reduction,' not as a cheap option for 'large-scale substitution,' and your mindset will be correct.

Figure 1 LCP precision connector and 5G communication components

The skills of the niche aristocrats lie entirely in being 'both thin and stable'

Why is LCP so precious? Just because of a few of its capabilities. The first is thin—it has excellent flowability and can be molded into long, thin-walled precision parts; those fingernail-sized connectors in phones wouldn't fit if it weren't thin. The second is stable—minimal dimensional shrinkage and low warpage, which is necessary to maintain tolerances in precision connectors. The third is heat-resistant—glass fiber reinforced LCP can withstand heat deformation temperatures around 280°C, so it can handle the high-temperature steps in SMT assembly. The fourth, and also the reason it is favored in 5G, is that it has extremely low dielectric loss, which means minimal signal attenuation for high-frequency transmission, making it ideal for millimeter-wave antennas and RF modules.

Speaking of the difficulties in LCP recycling, there are really quite a few. The first is that it’s delicate. LCP repeatedly heated will have changes in molecular orientation and glass fiber condition; after being re-blended a few times, its fluidity and rigidity differ from new material. The second is contamination. If a natural-colored sprue mixes with black material or other engineering plastics, the dielectric properties and heat resistance of the material cannot be maintained and it can only be downgraded and sold as ordinary modified material, causing its value to drop sharply. The third is the small quantity. The sprue material from a single factory in a month is just that much, not enough to make up a full batch, so recycling costs are high. Therefore, those doing LCP recycling have to strictly adhere to the six words: 'clean, single, traceable.' It’s better to collect a little less than to get the material contaminated— in this small business, reputation is more important than volume.

There's a trick here, which is the heat resistance level. In the LCP industry, it's commonly divided into E type, S type, and T type, with each level having higher heat resistance than the previous. For ordinary connectors, E type might be sufficient; to go through SMT reflow soldering, you need S type; and for components that are both high-frequency and high-temperature, only T type can handle it. The same principle applies to recycled materials—don't try to use E type sprues for tasks that require T type, as they will deform during reflow soldering. So when asking about recycled LCP, first clarify which heat resistance level it is and how much glass fiber it contains, rather than just placing an order based on the 'LCP' label—even within LCP, a difference in level can mean a big difference in price and suitable applications.

Precisely because it carries so many delicate tasks, LCP recycling has its particularities: you can't handle it recklessly. Unlike other recycled materials, if you mix in too much or if the material is dirty, its precious dielectric properties and heat resistance will drop—and these are exactly the reasons customers buy it. Therefore, recycled LCP cannot be treated as common stock; it can only be blended in parts with less stringent requirements or mixed with virgin material in small proportions. The table below categorizes it according to glass fiber content and heat resistance grade.

Level	Main Sources / Forms	Key indicators	Typical uses
LCP Natural Color Sprue (30% Glass Fiber)	Connector injection molding natural color gate	About 30% fiberglass, natural color	High-speed connector back mixing
LCP 40% glass fiber reinforced	High-rigidity structural component gate	About 40% fiberglass, high rigidity	Structural components, modified reuse
LCP Type E Heat-Resistant	Medium heat-resistant water gate	Type E Heat-Resistant	General electronic connector
LCP S-type heat-resistant	High heat-resistant nozzle	S-type heat-resistant	SMT reflow soldering parts
LCP T-type heat-resistant	High heat-resistant sprue	T-shaped heat-resistant	High-frequency, high-temperature parts
LCP Black Recycled Modification	Black Water Gate/Recycled Modification	Downgrade for use after modification	Parts with low performance requirements

Explanation: Regenerated LCP mainly uses injection molding sprue material and modified recycled material. Currently, the market circulation is small, and it is mainly recycled through specific channels. Grades and physical properties are based on the manufacturer's official TDS; glass fiber content and heat-resistant E/S/T classification are common industry standards, while specific grades and dielectric properties need to be confirmed according to test reports.

Recycle and modify water inlet materials; adding just a little saves a lot

LCP new material is expensive, costing tens to hundreds of yuan per kilogram. In factories that make precision parts, the sprues and runners cut off in the workshop every day may seem insignificant, but accumulated over time, they become a significant amount of money. Collecting these clean sprues, granulating and modifying them, and then mixing a small proportion back into the new material, or using them in lower-grade applications, saves real, tangible money.

Cost items	With brand new LCP	Blended Recycled Modified LCP	Difference Explanation
Raw material unit price	The price of new materials is high	Recycled water is somewhat cheaper	Diluted according to blend ratio
Water outlet treatment	When discarded as waste or sold cheaply	Recycled granulation modification and reuse	Turning scraps into treasure
Mixing ratio	——	Small-scale blending, try it first	Mix more dielectric/heat-resistant
Batch stability	Stable	Batch needs to be verified and TDS checked	Niche material batches have large fluctuations
Applicable parts	High-end high-frequency components	mid-to-low-end or non-critical components	Be cautious when mixing key components
General account	High cost	Save a bit, control risk	It's worth it if you know how to use it

Taking this account into consideration, the boundary list below helps you determine whether recycled LCP should be mixed in and where to mix it.

Suitable for blending: for parts with less stringent dielectric and heat resistance requirements, a small proportion can be compounded with new material to reduce costs.

Don't be greedy with the amount: if you add too much recycled LCP, the dielectric properties and heat resistance will drop. The key is, don't take risks with high-frequency components.

Identify the source: Only accept clean, natural-colored water inlets; do not accept mixed colors, mixed materials, or inlets with oil contamination.

Lock channels: For low circulation, secure materials in advance with fixed channels, don't scramble to find goods at the last minute.

First do a sample run: for each batch of recycled material, first test the dielectric properties and molding. Only proceed to full production when it's stable; don't go straight to mass production.

A reminder for factories wanting to try recycled LCP: don’t rush straight into mass production. Start with a small batch for samples and test three things—whether the dielectric constant is stable, whether the melt index is suitable, and whether the appearance and dimensions from injection molding are acceptable. Once these three pass, then discuss blending ratios. Small-volume specialty materials can vary between batches, so if you don’t check each batch, you might only find out on the production line that the flow isn’t right or the mold isn’t filling properly—rework losses could exceed the money saved on materials. Experienced factories always start with samples, check the data, and then run the machine; they never rely on experience to gamble.

The sprues from the connector factory are specifically collected by someone who comes to pick them up.

Let me give a typical scenario example: Ningbo Kolon New Materials Co., Ltd. has handled some factories with niche materials like LCP. Below, it is reconstructed according to common situations in the industry.

There is a factory in South China that makes high-speed connectors for mobile phones. They use new LCP material with 30% glass fiber, and their monthly usage is considerable. Every day, a lot of natural-colored sprue material piles up from injection molding on the shop floor. Previously, this sprue was either mixed in a little for reuse or disposed of cheaply as scrap. The boss also knows that LCP is expensive, but has never taken the sprue seriously—it's a small amount, scattered, and there isn’t time to sort it separately.

In a desperate situation, they consulted Kolon New Materials with a 'why not give it a try' mindset. Kolon New Materials got straight to the point: the circulation of recycled LCP is small and relies on specific channels, but your clean natural-color runners are exactly the material others are scrambling for. The suggestion was: collect the natural-color runners separately, don't mix them with other materials, pelletize them, and blend them with new material in a small proportion. Start by using this on non-critical parts with slightly lower dielectric requirements; for key high-frequency parts, still use new material, don't gamble with recycled material. First, make a sample to check dielectric properties and molding; once stable, then increase the quantity.

Later, this factory built a separate hopper for LCP sprues: natural-colored sprues didn’t touch the floor, weren’t mixed with materials from other workshops, and once a batch was accumulated, they would notify Kolon New Materials to pick it up; after pelletizing, samples were sent first to test dielectric constant and melt index, and only if the curves matched the new material would they dare to run it on the machine. In the first year, the volume was small, and gradually they connected sprues from several neighboring factories to form a stable supply. The boss said this is completely different from collecting miscellaneous materials before; it requires a steady, long-term approach. What Ningbo Kolon New Materials Co., Ltd. values is precisely this kind of long-term, clean, traceable source of niche materials.

After calculating this account, the boss felt more and more that he had underestimated this pile of sprues at the beginning. He did some math for Kolon New Materials: in the past, one kilogram of sprues was sold cheaply for just a few cents. Now, by collecting them separately, modifying them, and mixing them back in, it's like lowering the cost of one kilogram of new material. Over a year, the money saved on materials is enough to support half a work team. More importantly, using new material for critical parts avoids risks, while boldly reducing costs for non-critical parts does not delay either side. He said, the biggest fear in making small materials is not that they are expensive, but that even if they are expensive, you can't buy them, and even if you buy them, they are not stable — both issues can be solved by finding the right channel.

After doing it, the factory no longer sells sprue material cheaply, and mixing it back into the production line also saves a chunk of money on new materials. The boss said that he used to think that the LCP volume was too small to bother with, but now he realizes that precisely because it is expensive and niche, capturing clean sprue material is more valuable. After working with specialty materials for a long time, one gets this insight: recycling niche materials doesn't earn money from volume; it earns money by holding onto both 'cleanliness' and 'know-how.' This is also why Ningbo Cologne New Material Co., Ltd. insists on only accepting clean, natural LCP sprue material and securing inventory through channels—since the volume is small, they cannot afford to damage their reputation.

The amount of recycled LCP is small and the price is high; it only makes sense when used in the right place.

The amount of recycled LCP is small and the window is narrow. Save the scene comparison below to your phone, and when selecting materials, refer to it one by one, checking each item carefully. Don’t miss any of them. Don’t be greedy; using them in the right place is proper. This table isn’t meant for you to accept everything as it is; it’s meant to help you identify potential issues: which parts can be mixed, which parts should be avoided, so you have a clear idea beforehand. Then you can go look for sources to sample, avoiding repeated back-and-forths and delays in delivery, which would be truly unprofitable.

Ultimately, the recycled LCP business is played differently from ordinary recycled plastics. Ordinary materials compete on large volume, low price, and high turnover; this one competes on cleanliness, traceability, and strong channels. If you approach collecting LCP with the mindset of collecting PP, you'll most likely end up with a bunch of mixed, low-quality material that you can't sell for a good price and will be stuck with. On the other hand, if you can secure stable, clean supply from a few big manufacturers over the long term, this small business becomes an irreplaceable source of income. 5G volume is still increasing, and LCP demand will only grow. Now is the perfect time to build channels and reputation. If you wait until 5G materials are everywhere, trying to enter the market later, the barriers will have already been taken.

Application scenario	Recommendation Level	Precautions	When not to use
High-speed connector back mixing	Natural Color Water Gate 30% Fiberglass	small proportion blending	Don't use all key high-frequency parts
Modification of structural components	40% glass fiber reinforced	Batch rigidity testing	Do not use thin-walled high-flow parts incorrectly
SMT reflow components	S-type heat-resistant	Must be heat-resistant	If you can't handle the heat, don't force it.
high-frequency high-temperature component	T-shaped heat-resistant	Look at the dielectric report	Do not use the machine without testing
Cost reduction for non-critical components	Black Recycled Modified	Downgrade use	Do not use if appearance/performance is highly required
Want to buy as needed	Don't expect	Small circulation requires channel locking	Temporarily finding goods is prone to supply interruption

A small quantity doesn't mean no business; a niche and exclusive market is still a piece of meat.

Choosing materials for LCP, when the quantity is small and the door is narrow, you need to find the right person even more
