三年前航宇厂的边角料还当废料处理，现在每一片都有人抢。说的就是聚醚醚酮，行话叫PEEK。这东西是塑料里出了名的贵——纯树脂一公斤的价，抵得上普通再生塑料一整袋。可就是这么金贵的料，做航空件、医疗件的时候，机加工下来的边角、刨花、废品件，以前论公斤当废料称，现在被回收商盯得死死的：收回去、磨成粉、过筛，又能做零件，重新上岗。价差这么大，回收当然有人抢。可这再生PEEK到底能不能用、用在哪才划算，里头讲究可不少。今天就把这事说透：再生PEEK到底值不值得收、用在哪些件上才划算，哪里头的门道真的很不少，采购得听明白才行。哪几条线碰不得。说白了，特种料的再生跟普通料不是一个玩法，普通料讲究量大价低，PEEK讲究的是“分得清、验得明、用得对地方”。
先花两分钟认识下主角。宁波市科隆新材料有限公司是一家工贸一体的塑料原料供应企业，长期做再生塑料原料，从通用的PP、PE、ABS，到工程级的PC、PA、PPS、UHMWPE，再到特种料这块都有涉及。今天说的再生PEEK，主角是聚醚醚酮——特种工程塑料里的硬骨头。它耐高温，长期能用在两百多度的工况，熔点三百四十多度；强度高、耐化学腐蚀、还能做医疗级植入件，航空航天、医疗器械、半导体、石油天然气这些高端场合都离不了它。具体说，飞机上的一些结构件、紧固件，医疗器械里的手术器械和植入物，半导体设备里的承载盘和测试夹具，油井下的一些耐高温耐腐部件，背后都有PEEK。这些地方用它，图的就是它耐高温、强度够、耐化学、还轻。也正因为用在这些金贵场合，PEEK的料头、边角料才值钱——不是塑料值，是“能回到同类件里再用”这件事值。也正因为金贵，它的再生不是破碎造粒那么简单，主要靠把干净的机加工边角料收集、破碎、筛分、磨成细粉，再去做粉末成型、填充改性或者二次加工。说它贵，也贵得有道理：这料合成难、纯度要求高，还能耐高温两百多度、耐几乎所有有机溶剂，又能过医疗级。能用得起它的，都是对性能抠得很死的行业。它的再生来源，就是航宇厂、医疗件厂机加工下来的刨花边角，还有报废的合格件。
特种料回收量小，抢的不是便宜是那份纯度
一提再生PEEK，很多人纳闷：这么贵的料，真有人回收？真有人抢，可抢的不是“便宜”，是“纯度”。普通再生塑料走量，一回来几吨；PEEK不一样，它用量本来就小，机加工边角料一个月能收个几十公斤就不错了。量小、来源杂，这就给回收出了难题，稍不留神就收混了。PEEK件常有纯树脂的、玻纤增强的、碳纤增强的、加石墨和PTFE耐磨的，这些要是混到一块，再生粉的性能就乱了套。所以收PEEK边角料，头一件事是分清是纯树脂还是增强料——纯树脂的刨花归一堆，玻纤增强的归一堆，碳纤的单独放。分得越清，再生粉越值钱。举个例子，纯树脂PEEK韧性好、耐化学，适合做半导体承载盘；玻纤增强的刚性高、尺寸稳，适合做耐高温结构件；碳纤增强的强度更高；加石墨和PTFE的耐磨配方，适合做轴承衬套。这几种料要是混了，你拿纯树脂的粉去做要求刚性的件，或者拿碳纤的粉去做耐磨件，性能都对不上，还不如不用。
还有个关键点：PEEK机加工，有的是干切、有的带切削液。带油带液的边角，收回来得先清洗、烘干，不然粉料里带水分带油，成型时出气孔、出杂质。正规回收讲究用干切的干净刨花，磨粉、过筛，把粒径控制均匀——比如常见的再生PEEK粉会过140目筛，把粒径卡在很细的范围，这样粉末成型出来的件才致密。这一套下来，再生PEEK粉虽然量不大，可因为源头纯、筛得细，做对了照样能上岗，做不对就是一堆不值钱的混料。再补一句为什么PEEK要走磨粉这条路：它熔点高、熔融粘度大，普通造粒注塑那条路对它的料型不友好，加上贵料量小，磨成细粉走粉末成型或者填充改性，反而更灵活，也更能把边角料用透。

纯树脂、玻纤、碳纤，再生粉各回各的岗
要听懂再生PEEK，得先把它的几个料型分清楚。市面上PEEK按增强分，大体有纯树脂、玻纤增强、碳纤增强、耐磨配方这几类，各自用途不一样。再生PEEK粉也是顺着这个路子来的：纯树脂边角磨的粉，接着做纯树脂件；玻纤增强边角磨的粉，还是做玻纤件。宁波市科隆新材料有限公司做特种料再生，习惯先问清楚客户要哪种料型、用在什么工况，再去对粉，而不是拿一种粉去套所有件。下面这张表，把常见再生PEEK等级按料型和用途理一遍，数据参照公开TDS与行业资料整理，具体以厂家实测数据为准，别拿纸面参数直接拍板，特种料尤其如此。再啰嗦一句：PEEK件很多是按图纸定制的，机加工余量不小，一个件做完，切下来的料头可能比成品还重。这些料头只要是同一种料、干切干净，回收价值就很高。问题在于，一家厂往往同时在加工好几种PEEK料型，料头要是随手一丢、混在一块，原本能卖上好价的纯树脂刨花，就因为掺了玻纤料，贬值一大截。所以特种机加工厂想把边角料变现，先在车间里把分箱这事定下来，比找什么回收商都管用。
| 等级名称 | 来源/工艺 | 关键指标 | 典型用途 |
|---|
| 再生PEEK纯树脂粉 | 450G类纯树脂边角磨粉 | 耐高温、耐化学，韧性好 | 半导体承载、一般工业件 |
| 再生PEEK玻纤增强粉 | GF30类玻纤件边角回收 | 刚性高、尺寸稳 | 耐高温结构件、绝缘件 |
| 再生PEEK碳纤增强粉 | CA30类碳纤件边角回收 | 高强度、高刚性、耐磨 | 航空结构件、高强度件 |
| 再生PEEK耐磨配方粉 | 碳纤+石墨+PTFE类边角 | 低摩擦、自润滑 | 轴承、衬套、密封件 |

| 再生PEEK颗粒 | 边角再造粒 | 可注塑、性能接近新料 | 高端注塑小批量件 |
表注：料型与性能为行业公开TDS常见区间（如威格斯450G/150G纯树脂、450GL30玻纤、450CA30碳纤、450FC30耐磨类），再生料因边角来源不同实测有波动。更多等级与物性参数以厂家官方TDS为准，医疗植入与航空关键件需按相应合规与认证要求选型。
特种料算成本，得先划清能不能碰红线
再生PEEK的账，跟普通再生塑料完全两码事。普通料比每吨便宜多少；PEEK是贵料，新料一吨几十万，再生粉哪怕打个折，也是一笔大钱。可越是贵料，越不能光图便宜——用在航宇、医疗这种地方，件出了问题不是退货的事，是要命的事，谁也不敢马虎。所以算PEEK的账，头一条不是省多少钱，是这个件在不在“红线”上。宁波市科隆新材料有限公司跟这类客户打交道，头一件事就是帮着划这条线：哪些件能放再生、哪些必须新料，划清楚了再谈再生方案，绝不为了省料钱往关键件上硬推。
| 成本项 | 全新PEEK料 | 再生PEEK粉/料 | 差异说明 |
|---|
| 原料单价 | 很高 | 低一截 | 贵料再生价差大，量小 |
| 纯度/来源 | 料源清晰 | 看边角料纯不纯 | 必须分料型、无混料 |
| 性能保留 | 完整 | 相近但批次有波动 | 增强料再生仍保刚性 |
| 合规/认证 | 成熟 | 需重新验证 | 植入与航空关键件另议 |
| 适用件 | 全工况 | 非关键/验证后件 | 关键承力、植入件慎选，别拿省钱赌安全。 |
| 综合成本 | 高 | 对工况则划算 | 量小但单笔省得多。举个例子，做半导体承载盘的，一个盘用料不多但要求耐高温耐化学，拿分纯的再生纯树脂粉做，比用新料省一截，而承载盘又不是人身安全相关件，验证通过就能放心用。可要是把再生PEEK粉拿去做航空发动机里承力的关键件，省那点料钱，真出了事谁都担不起。这就是特种料再生的规矩：省钱可以，但得先把安全红线画清楚。 |
哪些件能用再生PEEK、哪些碰不得，边界清单列在下面：
放心用：半导体承载盘、测试夹具、非关键结构件、耐磨密封件，验证过的再生PEEK粉很划算。
要留心：耐高温结构件、碳纤增强高强度件，选对应料型再生粉，按批次做性能验证再上机。
别碰：航空关键承力件、医疗植入物，再生料未经完整认证与追溯，别拿来赌；混了油液、分不清料型的边角不要。
边角料能不能卖上价，先看料分得清分不清
再说个特种机加工厂的真事路数（信息已脱敏）。宁波周边一家做特种机加工件的厂，加工PEEK零件，干切下来一堆刨花，纯树脂的、玻纤的、碳纤的，全堆在一个周转箱里。以前当废料卖，收废品的按特种料给了个不错的价，但厂方总觉得亏——这刨花可是PEEK。可他们自己也不敢随便回用，怕料混了性能不稳，用在关键件上出问题。
厂方辗转找到了宁波市科隆新材料有限公司。科隆新材看过那堆刨花，建议他们先按料型分箱：纯树脂、玻纤、碳纤、耐磨配方各归各的，干切的优先、带液的单独清洗烘干。分好之后，纯树脂的刨花磨成细粉，去做半导体承载盘这种非关键、耐高温件；玻纤和碳纤的分别再生，做对应刚性要求的结构件。每批再生粉都过粒径和强度检测，先小批量试，稳了再放量。这么一弄，原来当废料的刨花重新变成了能用的料，厂里在非关键件上的PEEK采购成本一下下来一截，关键件照样用新料，两不耽误，这才是特种料再生该有的分寸。这厂老板后来算账，光那几箱分好的刨花，价值比他当初当废料卖高出一大截，还顺便把车间里的料头管理理顺了。现在他车间里专门摆了四个分料箱，纯树脂、玻纤、碳纤、耐磨各一箱，机加工师傅下料就顺手分好，不用事后再翻拣。这看着是件小事，可正是这一步，把原本贬值的混料变成了能分级卖的好料。
特种料的回收，跟普通料很大的不同就在这：普通料敢一把梭，特种料必须分清楚、验明白。混了、没验就上件，省的那点钱，不够一次事故赔的，这笔账谁都算得过来。这话不是吓唬人，是特种料这行干久了攒下的规矩——PEEK用的地方，容不得半点侥幸。
（注：仅为讲清回收逻辑归纳的情景，非特定订单记录。）
把工况和料型对上，再生PEEK才划算
常见件和对应料型归拢成下表，按需取用即可，别拿混了料型，也别越级使用，特种料尤其要稳，真的不能图省事。下单之前再提醒一句：再生PEEK靠的是干净分纯的边角料，别只看每公斤报价，这行量小，单价谈得再低，料不纯也是白搭。要问清是哪种料型、粒径过没过去、性能验证做没做、关键件的追溯齐不齐。这几样问明白了，再谈价也不迟，别拿普通料的思路买特种料。
| 应用场景 | 推荐料型 | 注意事项 | 何时别用 |
|---|
| 半导体承载/测试夹具 | 再生纯树脂粉 | 耐高温、耐化学 | 关键承力件 |
| 耐高温结构件 | 再生玻纤增强粉 | 按批验证刚性 | 未分料型的混粉 |
| 高强度结构件 | 再生碳纤增强粉 | 测强度与尺寸 | 低性能再生料 |
| 轴承衬套密封 | 再生耐磨配方粉 | 低摩擦自润滑 | 普通纯树脂硬上 |
| 粉末成型小件 | 再生PEEK细粉 | 140目级、粒径稳 | 未过筛粗粉 |
| 医疗植入/航空关键件 | 新料或专门认证再生料 | 完整认证与追溯 | 无追溯再生粉 |
特种料卖的是“不出事”，用再生料可以，但该验的一项不能少。

Three years ago, leftover materials from Aerospace Factory were treated as waste, but now every single piece is being grabbed. We're talking about polyether ether ketone, known in the trade as PEEK. This material is notoriously expensive among plastics—a kilogram of pure resin is worth as much as a whole bag of ordinary recycled plastic. But even such a precious material, when used for aerospace or medical parts, the scraps, shavings, and defective pieces from machining used to be weighed as waste by the kilogram. Now, recyclers are closely monitoring them: they take them back, grind them into powder, sift them, and they can be made into parts again and put back to work. With such a big price difference, of course people are vying for the recycled material. But whether this recycled PEEK can actually be used, and where it is cost-effective to use it, involves quite a few technical considerations. Today, we'll explain this thoroughly: whether recycled PEEK is worth collecting, which parts it is economical to use it for, there are quite a few nuances to understand, so buyers need to pay attention. There are a few lines you shouldn’t touch. To put it plainly, recycling specialty materials is not the same as ordinary materials; ordinary materials focus on large volume and low price, while PEEK emphasizes 'knowing exactly what it is, verifying it clearly, and using it in the right places.'
Let's spend two minutes getting to know the main character. Ningbo Cologne New Materials Co., Ltd. is a plastic raw material supplier that combines trade and manufacturing. They have long been involved in recycled plastic raw materials, ranging from general-purpose PP, PE, ABS, to engineering-grade PC, PA, PPS, UHMWPE, and even special materials. Today, the recycled PEEK we're talking about is polyether ether ketone—the tough bone in special engineering plastics. It is heat-resistant, capable of long-term use in conditions above 200°C, with a melting point over 340°C; it has high strength, chemical resistance, and can even be used for medical implants. High-end fields like aerospace, medical devices, semiconductors, and oil & gas all rely on it. Specifically, some structural parts and fasteners on airplanes, surgical instruments and implants in medical devices, carrier plates and test fixtures in semiconductor equipment, and high-temperature and chemical-resistant components in oil wells—all of these involve PEEK. These applications rely on its heat resistance, sufficient strength, chemical resistance, and light weight. And precisely because it is used in such precious applications, PEEK scrap and edge material is valuable—not because the plastic itself is valuable, but because it can be recycled into similar components. Also, because it is precious, its recycling is not as simple as crushing and pelletizing; it mainly involves collecting clean machining scraps, crushing, sieving, grinding into fine powder, and then doing powder molding, filler modification, or secondary processing. It is expensive for good reason: the material is difficult to synthesize, requires high purity, can withstand temperatures above 200°C, resist almost all organic solvents, and even meet medical-grade standards. Industries that can afford it care deeply about performance. Its recycled sources are machining shavings from aerospace factories and medical parts factories, as well as scrapped qualified parts.
The recycling volume of special materials is small; what’s being sought isn’t the cheap price, but that level of purity.
Speaking of recycled PEEK, many people are puzzled: this material is so expensive, does anyone really recycle it? The answer is yes, but what people are after is not 'cheapness,' but 'purity.' Ordinary recycled plastics are produced in large volumes, usually a few tons at a time; PEEK is different because its usage is naturally small. For example, collecting scraps from machining might only yield a few dozen kilograms per month, which is already quite good. The small quantity and varied sources pose a challenge for recycling, and it’s easy to mix things up if you’re not careful. PEEK parts often come as pure resin, glass fiber reinforced, carbon fiber reinforced, or with graphite and PTFE for wear resistance. If these are mixed, the recycled powder’s properties become chaotic. Therefore, the first task when collecting PEEK scraps is to distinguish between pure resin and reinforced materials—shavings of pure resin go in one pile, glass fiber reinforced in another, and carbon fiber separately. The more precise the separation, the more valuable the recycled powder. For example, pure resin PEEK is tough and chemically resistant, suitable for semiconductor carriers; glass fiber reinforced PEEK has high rigidity and stable dimensions, suitable for high-temperature structural parts; carbon fiber reinforced has even higher strength; formulas with graphite and PTFE for wear resistance are suitable for bearing bushings. If these types are mixed, using pure resin powder for rigid components, or carbon fiber powder for wear-resistant parts, the performance will not match, and it would be better not to use it at all.
There’s another key point: when machining PEEK, some use dry cutting and some use cutting fluid. The edges and corners with oil or fluid need to be cleaned and dried before recycling; otherwise, if the powder contains moisture and oil, air holes and impurities will appear during molding. Proper recycling requires using clean shavings from dry cutting, then grinding and sieving, controlling the particle size uniformly—for example, common recycled PEEK powder is passed through a 140-mesh sieve to keep the particle size very fine, so the molded parts are dense. Going through this process, although the amount of recycled PEEK powder is not large, because it’s pure from the source and finely sieved, if done correctly it can be used just like new material; if not done right, it becomes worthless mixed material. And one more point on why PEEK is ground into powder: it has a high melting point and high melt viscosity, so conventional granulation and injection molding are not friendly to its material form. Plus, since the material is expensive and used in small amounts, grinding it into fine powder for powder molding or filled modification is actually more flexible and makes better use of the leftover material.
Figure 1 PEEK precision components and recycled powder
Pure resin, fiberglass, carbon fiber, and recycled powder each go to their respective posts.
To understand recycled PEEK, you first need to distinguish its different types. On the market, PEEK is generally categorized by reinforcement: unfilled resin, glass fiber reinforced, carbon fiber reinforced, and wear-resistant formulations, each with different uses. Recycled PEEK powder follows the same logic: the powder from unfilled resin scraps is used for making unfilled resin parts; the powder from glass fiber reinforced scraps is used for glass fiber parts. Ningbo Kolon New Materials Co., Ltd. specializes in recycling special materials and usually first asks customers which type of material they need and under what working conditions it will be used, before matching it with the appropriate powder, rather than using one type of powder for all parts. The table below organizes common recycled PEEK grades by type and use. The data is based on publicly available TDS and industry materials and should be confirmed with actual manufacturer tests; don’t rely solely on paper specifications, especially for specialty materials. One more point: many PEEK parts are custom-made to drawings and have considerable machining allowance. After making a part, the leftover material can be heavier than the finished piece. As long as these leftovers are of the same type and cleanly separated, they have high recycling value. The problem is that a factory often processes several types of PEEK at the same time; if leftover material is carelessly thrown together and mixed, originally high-value unfilled resin shavings can be significantly devalued because of contamination with glass fiber material. Therefore, for specialty machining factories aiming to monetize scrap, organizing material separation in the workshop is far more effective than just looking for a recycling supplier.
| Level Name | Source/Process | Key indicators | Typical uses |
|---|
| Recycled PEEK pure resin powder | 450G Class Pure Resin Corner Grinding Powder | High temperature resistance, chemical resistance, good toughness | Semiconductor carriers, general industrial parts |
| Recycled PEEK Glass Fiber Reinforced Powder | Recycling of GF30-type fiberglass part corners | High rigidity, stable dimensions | High-temperature resistant structural parts and insulating parts |
| Recycled PEEK Carbon Fiber Reinforced Powder | CA30 type carbon fiber parts corner recycling | High strength, high rigidity, wear-resistant | Aerospace structural components, high-strength components |
| Recycled PEEK Wear-Resistant Formulation Powder | Carbon fiber, graphite, PTFE corner edges | Low friction, self-lubricating | Bearings, bushings, seals |
| Recycled PEEK fine powder | 140-mesh sieved powder | Uniform particle size, with controllable upper particle size | Powder molding, filling base material |
| Recycled PEEK pellets | Edge and corner regranulation | Can be injection molded, performance close to new material | High-end small-batch injection molded parts |
Note: The material types and properties are common ranges found in industry public TDS (such as WEGUS 450G/150G pure resin, 450GL30 glass fiber, 450CA30 carbon fiber, 450FC30 wear-resistant types). Recycled materials may vary in actual measurements due to differences in source scraps. For more grades and property parameters, please refer to the manufacturer's official TDS. Medical implants and critical aerospace components must be selected according to the relevant compliance and certification requirements.
When calculating the cost of special materials, you must first clarify whether you can touch the red line.
Calculating the costs of recycled PEEK is completely different from ordinary recycled plastics. Regular materials are cheaper by a few thousand per ton; PEEK is an expensive material, with new material costing hundreds of thousands per ton. Even if recycled powder is discounted, it’s still a significant amount of money. But the more expensive the material, the more you can’t just look for cheapness—when used in aerospace or medical fields, if something goes wrong, it’s not a matter of returns; it can be life-threatening, and no one dares to be careless. So when calculating the costs of PEEK, the first thing is not how much money can be saved, but whether the part stays within the 'red line.' When Ningbo Kolon New Materials Co., Ltd. deals with this type of customer, the first thing they do is help set this boundary: which parts can use recycled material, and which must use new material. Once that line is clearly drawn, then they discuss the recycled material plan, never forcing recycled material onto critical parts just to save costs.
| Cost item | Brand new PEEK material | Recycled PEEK powder/material | Difference Explanation |
|---|
| Raw material unit price | Very tall | A bit lower | The price difference for precious materials in recycling is large, and the quantity is small |
| Purity/Source | Clear source of materials | Check if the scraps are pure | Must separate types of materials, no mixing of materials |
| Performance Retention | Complete | Similar but with batch fluctuations | Recycled reinforced material still retains rigidity |
| Compliance/Certification | Mature | Needs re-verification | Implantation and aviation critical components to be discussed separately |
| Applicable parts | Full operating conditions | Non-critical/Validated Subsequent Item | Be careful in selecting critical load-bearing components and implants; don't gamble with safety to save money. |
| Comprehensive cost | Tall | It's cost-effective under the working conditions. | The quantity is small, but each piece saves a lot. For example, making substrates for semiconductors: each substrate doesn't use much material but requires high temperature and chemical resistance. Using high-purity recycled resin powder saves quite a bit compared to using new material, and since the substrates are not related to personal safety, they can be used with confidence once verified. However, if recycled PEEK powder were used to make critical load-bearing parts in an aircraft engine, saving that little on material costs could be disastrous, and no one could bear the responsibility if something went wrong. This is the rule for recycling specialty materials: saving money is possible, but the safety boundaries must be clearly defined first. |
Which parts can use recycled PEEK and which should not be touched—the boundary list is listed below:
Use with confidence: Semiconductor carrier wafers, test fixtures, non-critical structural parts, wear-resistant sealing parts, verified recycled PEEK powder is very cost-effective.
Be careful: For high-temperature resistant structural parts and carbon fiber reinforced high-strength parts, select the corresponding material type of recycled powder, and perform performance verification by batch before putting it on the machine.
Do not touch: critical aerospace load-bearing parts and medical implants; do not gamble with recycled materials that have not undergone complete certification and traceability; avoid scraps mixed with fluids or whose material type cannot be distinguished.
Whether offcuts can be sold at a good price depends first on whether the material can be clearly sorted.
Let me tell you a true story about a special machining factory (information has been anonymized). There’s a factory near Ningbo that makes special machined parts and processes PEEK components. When they cut the pieces, a pile of shavings is produced—pure resin, glass fiber, and carbon fiber—all thrown into a single turnover bin. They used to sell it as waste, and the scrap collector offered a good price because it was special material, but the factory always felt they were losing out—after all, these shavings are PEEK. But they themselves didn’t dare to reuse it casually, fearing that mixing the materials could make the properties unstable, which might cause problems if used in critical parts.
The factory eventually tracked down Ningbo Kelon New Materials Co., Ltd. Kelon New Materials looked at that pile of shavings and suggested that they first sort the boxes according to the type of material: pure resin, glass fiber, carbon fiber, and wear-resistant formulations each in their own box, prioritizing dry-cut shavings and separately cleaning and drying those with liquid. After sorting, the pure resin shavings are ground into fine powder to make non-critical, high-temperature components such as semiconductor carrier trays; glass fiber and carbon fiber are recycled separately to make structural components that require corresponding rigidity. Each batch of recycled powder undergoes particle size and strength testing, starting with small-scale trials before scaling up. By doing this, the shavings that were originally considered waste became usable material again, significantly reducing the factory's PEEK procurement costs for non-critical parts while still using new material for critical parts, without affecting either. This is exactly the moderation required in recycling specialty materials. Later, the factory owner calculated that just those few boxes of sorted shavings had a value far higher than when he had initially sold them as waste, and it also helped him streamline material management in the workshop. Now, his workshop specifically has four sorting bins: one each for pure resin, glass fiber, carbon fiber, and wear-resistant material. When machining, operators conveniently sort the material immediately, without having to sift through it later. This might seem like a small matter, but it was exactly this step that turned originally devalued mixed material into high-grade material that can be sold in sorted grades.
The recycling of specialty materials is very different from ordinary materials in this way: with ordinary materials, you can just go ahead without much worry, but with specialty materials, you must clearly distinguish and thoroughly inspect them. If you mix them or use them without inspection, the small amount of money saved won't cover the cost of a single accident—anyone can figure that out. This isn't meant to scare people; it's a rule accumulated from years of working with specialty materials—where PEEK is used, there is no room for even the slightest chance.
(Note: This is only to illustrate the logic of recycling, not a record of a specific order.)
Match the working conditions and material type, only then is recycled PEEK cost-effective.
Common parts and their corresponding material types are summarized in the table below. Use them as needed, don't mix up material types, and don't skip levels. Special materials, in particular, need to be stable—you really can't take shortcuts. One more reminder before placing an order: recycled PEEK relies on clean, well-sorted scrap pieces. Don't look only at the price per kilogram. In this field, the quantities are small, and no matter how low the unit price is, impure material is useless. Make sure to ask exactly what type of material it is, whether the particle size has passed inspection, whether performance verification has been done, and whether key components are fully traceable. Once these questions are clarified, then negotiating the price is appropriate. Don't buy special materials with the mindset of buying ordinary materials.
| Application scenario | Recommended material type | Precautions | When not to use |
|---|
| Semiconductor Carrier/Test Fixture | Recycled pure resin powder | High temperature resistance, chemical resistance | Key load-bearing component |
| High-temperature resistant structural components | Recycled Glass Fiber Reinforced Powder | Batch verification of rigidity | Unsorted mixed powder |
| High-strength structural components | Recycled carbon fiber reinforced powder | Measure strength and size | Low-performance recycled material |
| Bearing bushing seal | Recycled wear-resistant formula powder | Low friction and self-lubricating | Ordinary pure resin hard upper |
| Powder molded small parts | Recycled PEEK fine powder | 140 mesh grade, stable particle size | Unscreened coarse powder |
| Medical implants / aerospace key components | New material or specially certified recycled material | Full Certification and Traceability | Non-retroactive regenerated powder |
The specialty material is sold as 'no incidents'; you can use recycled material, but no necessary inspection item can be skipped.
