再生POE：光伏胶膜边角料里的“低调降本料”

三年前为了省那点料钱，挑了脆生生的回料；三年后退货单摞起来，把当初省下的连本带利还了回去，还搭进去客户的信任。这种账，做周转箱、做汽车内饰的老板没少算。今天要说的再生POE，就是专门来解这个死结的一味“药”，今天这味药怎么用、用在哪，一次讲清楚。

先花两分钟认识下主角。POE学名叫聚烯烃弹性体，是用茂金属催化把乙烯和辛烯、丁烯这类α-烯烃共聚出来的弹性体，外表白白净净，像颗软糖，捏得动、拉得长。它有个外号叫“万能增韧剂”——本身不算硬结构料，可往PP、PE里掺一点点，脆料就不那么脆了，抗摔抗冲能上好几个台阶。它还耐低温、耐候、和聚烯烃天生相容。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，POE是其中比较新、也比较低调的一个。

再生POE这个品类新，新到大多数人还没听过。它的再生来源很特别：主要不是旧鞋底、旧管材，而是光伏胶膜厂裁下来的边角料。光伏组件封电池片用的胶膜，现在大量用POE（尤其N型电池），生产时按组件尺寸裁切，下来一堆边条余料。这些料干净、耐候、又是刚从产线上下来的，回收造粒后性能保持得不错。宁波市科隆新材料有限公司在收这类料时，认准光伏胶膜边角料这个来源，不拿说不清来路的杂料凑。

POE不是拿来做主料的，是拿来当“药”的

不少人一听POE，以为它能单独注塑、做个箱子做个壳。真不是这么回事。POE的正确打开方式，是当“药”——量不用大，往脆的PP、PE回料里掺个百分之十几到三十，抗冲就蹭蹭往上走。

PP回料反复加工，分子链断了，做周转箱、打包带最怕摔，一摔就裂。往里加钙粉、加填充，只会越做越脆。这时候掺一点溶脂对得上的POE，等于在脆骨架里加了一层软筋，摔一下不断、折一下不开。行业里的数据是，PP里加百分之十几到三十的POE，冲击强度能提升好几倍。但注意，它是药不是饭：掺多了，材料的拉伸强度会往下掉，成本也上去了。这就是POE“掺一点就省不少”的道理——它的价值不在自己做多少件，在帮别的料少出废品。

所以再生POE的头一条认知是：别拿它当主料去比吨价，要拿它当增韧成本去算。你不是买一堆POE颗粒，你是买“把脆回料变合格料”的那把钥匙。想通这一点，再生POE为什么低调却值钱，就清楚了。

那POE为什么能增韧？靠的是它“两相”的本事。POE分子链里，结晶的硬段像骨架，无定形的软段像橡胶。把它掺进PP、PE里，软段分散成一个个小颗粒，受到冲击时这些软质点能吸收能量、挡住裂纹扩展，等于给脆料装了无数个微型减震器。而且POE和PP、PE都是聚烯烃，天生相性好，不用太多相容剂就能揉在一起，这也是它比别的增韧剂好用的地方。选POE关键看熔指（流动性），要跟基材对得上，否则掺进去浮在表面、分散不均，增韧就成了表面功夫。

除了做增韧剂，POE自己也是个多面手。汽车保险杠、内饰、耐低温容器，都爱掺它；电线电缆要低温柔韧的护套，用它；TPO防水卷材、鞋材发泡，也有它的身影。它透明时透光率能到九成以上、雾度低，这才被光伏挑中做封装膜。再生POE顺着这些应用走，干净的边角料回去做改性、做软质件、做发泡，都是顺理成章。说它“低调”，是因为它总躲在主料背后当配角，可离了它，一堆脆料和薄膜都不好做。

这也是为什么再生POE在市面上没那么高调：它既不是靠量大取胜的通用料，也不是人人都懂的老牌料。它的客户是那群做改性、做周转箱、做汽车内饰的厂，知道掺一点就能救活脆回料。外面的人看它平平无奇，里面的人却偷偷用它把成本和良率都按住了。对想在2026年继续降本的厂来说，这种“别人还没反应过来”的品类，往往才是真有油水的地方。

图1　光伏组件、胶膜与POE颗粒

光伏边角料里，藏着大半的再生POE

再生POE从哪来？这个问题本身就很有故事。它不像PP那样从千家万户的废旧制品里来，它的家底，主要在光伏厂的车间里。

光伏组件要把电池片封在两片玻璃之间，中间那层胶膜过去多用EVA，现在N型TOPCon、HJT这些高效电池，更爱用POE胶膜——因为POE水汽透过率低、电绝缘好、抗电位诱导衰减、耐湿热老化，户外放二三十年也稳，寿命比EVA更长。胶膜厂量产时，宽膜切成组件尺寸，裁下来的边条、换卷余料、试机料，都是干净的POE，几乎没沾杂质。这些边角料被专门回收、造粒，就成了市面上再生POE颗粒的主要来源。行业里长期有专门队伍上门收光伏厂的POE、EVA边条，就是这个生意。

这也解释了再生POE的另一个特点：它干净，但量不大、来源集中。因为它不是从消费后废品里广撒网收的，而是跟着光伏产业的扩产走——光伏胶膜产得多，边角料就多。正规再生的路子是：把光伏边条按材质分开（POE和EVA别混）、破碎、清洗、造粒，再按溶脂和用途分级。鞋材、汽车内饰、薄膜厂的POE边角料，也是补充来源。下面这张等级表，就是按来源和用途分的。

为啥光伏边条金贵？一是干净，胶膜厂刚切下来，没沾土、没混别的料；二是耐候，POE本来就是为户外二三十年设计的，抗紫外、耐湿热，这个底子再生后还在；三是来源集中，跟着光伏厂走，量稳定。当然也有讲究：光伏边条里POE和EVA常常挨在一起，还有PET复合边，分选时必须分开，混了就贬值。所以同样叫光伏膜边料，分得开POE单料的，和搅成一锅的，身价差着档次。

等级	主要来源	关键指标	典型用途
光伏胶膜边角料再生POE	光伏POE胶膜裁切余料	洁净，耐候低水汽，透明度较好	增韧改性、透明制品、光伏次料
增韧级再生POE	工厂水口、胶膜边条造粒	与PP/PE相容，提抗冲	PP/PE增韧、周转箱、打包带
汽车内饰再生POE	汽车内饰边角料	低温柔韧，手感好	汽车内饰、软质件
发泡级再生POE	软质件、鞋材边角料	可发泡，弹性好	发泡、缓冲、鞋材
吹膜级再生POE	POE薄膜边角料	透明，加工性好	吹膜、包装
通用掺混再生POE	多来源混合造粒	性能波动偏大	低档改性、填充掺混

说明：POE为较新的聚烯烃弹性体品类，再生目前主要参照GB/T 40006.1《塑料再生塑料第1部分：通则》及各生产企业的企业标准；光伏胶膜边角料是再生POE的主要来源，表中指标为行业公开资料与厂家技术数据归纳，更多等级与物性参数以厂家官方TDS为准。

掺一点POE省的，比整批换料还多

再生POE的降本逻辑，跟别的再生料真不一样。它不是让你把主料整个换掉，而是让你往脆回料里“点”那么一把，用量不大，却能把整件料的合格率拉上来。账就得这么算。

行情和产业上也能看出POE为什么“新”。POE长期被几家国际大厂垄断，价格不低，直到最近几年国内才陆续实现量产突破。正因为它本身贵、应用又火，光伏胶膜扩产带来的边角料就更显得金贵——这些干净的POE余料回收造粒后，价格比新料实在，增韧效果又不差，自然成了改性厂里抢着要的低调降本料。它不像PP、ABS那样人人都在做再生，知道的人不多，真正会用的更少，这反而给先上手的厂留出了成本空间。

成本项	新料POE	再生POE	差异说明
吨料价	较高	低一截	光伏边角料再生有价格优势
增韧效率	稳定	同源边角料尚可	杂料增韧效果波动
相容性	与PP/PE好	同源料相容好	杂料可能影响表面
耐候耐低温	好	光伏级边角料耐候好	普通料耐候一般
掺混比例	精确添加	按效果小步试	掺多了拉伸会掉
综合成本	基准	掺一点就省	过量反而降强度、增成本

结合这笔账，下面的边界清单帮你判断POE该掺在哪、别掺在哪。

适合用再生POE：PP/PE回料增韧改性；周转箱、打包带、汽车内饰提抗冲；耐低温、发泡缓冲件。

光伏组件封装：对耐候、透光、可靠性要求极高，普通再生POE别直接上，认准光伏级。

掺量别贪多：POE掺多了拉伸强度会掉，从小比例往上试，找到抗冲和强度的平衡点。

杂质先过滤：回料里的杂质不滤干净，再好的POE也救不了韧性。

高端光学、高可靠件：用普通再生POE要谨慎，新料更稳妥。

最后提醒一句：POE增韧是个“配比活”，不是“加料越多越好”。下单前先拿小批量打样，把你手里的回料、想要的抗冲水平、现有工艺温度告诉供应商，让对方帮你定POE的型号和掺量。熔指对不对、杂质滤没滤、掺量试没试，这三件事做扎实，再生POE才真能帮你把成本降下来又不出事。

周转箱摔不裂的秘密，在那一小把颗粒里

这件事在周转箱圈子里不新鲜，宁波市科隆新材料有限公司做周转箱料这行接触过不少，按典型情景示例来讲，人物厂名做了处理。

华东有家做周转箱的厂，用PP回料做箱子，成本压得很低，可客户反馈一到冬天、一摔就裂，边角全是白痕。老板想过加新PP、加填充，加新料成本下不来，加填充又更脆，卡在那儿好一阵。

后来他找到科隆新材。科隆新材看了他的料，先说别急着换主料，问题不在料便宜，在脆。给出的建议是：把回料里的杂质先滤干净，再掺一点增韧级再生POE，从小比例往上试，看跌落和低温冲击。POE选和PP相容性好、溶脂对得上的型号，掺到抗冲够、拉伸又不塌的那个比例就停。这样主料还是便宜的回料，只多花了一小把增韧剂的钱，箱子就不裂了。

科隆新材还提醒他，增韧这事要小步试：先拿百分之十试，看低温跌落；不够再加，加到抗冲够了就别往上堆。POE加多了，箱子是不裂了，可表面发软、尺寸跑偏、拉伸下降，成本也跟着上去。另外回料里的粉尘、金属屑一定要滤干净，杂质混在里面，POE再好也补不上那些硬伤。这批料的熔指也要跟现有产线对，熔指差太远，分散不均，做出来的箱子软硬不一。

试下来，箱子的开裂投诉明显少了，成本比全换新PP低一大截。POE这东西，用量不大，作用却像给脆料装了减震器。这也是宁波市科隆新材料有限公司推再生POE时，习惯先看你的料脆在哪、再配增韧比例的原因——它是来调结构的，不是来凑吨数、走过场的。

现在这家厂已经把再生POE当成常规配方的一部分，每批回料先测脆不脆、再定掺多少。回头看，当初摔裂的那些箱子，问题从来不是回料便宜，而是缺了那一小把把韧性补回来的弹性体。

POE增韧，掺多了是另一笔账

前面铺垫这么多，最后落回一张表，照着用不踩空。再生POE是个低调选手，用对地方四两拨千斤，用错地方花了钱还降性能，所以更得对着表来。

应用场景	推荐等级	注意事项	何时别用
PP/PE增韧	增韧级再生POE	掺10%-30%小步试	超量注意拉伸
周转箱/打包带抗冲	增韧级再生POE	先滤净杂质	杂料别用
汽车内饰软质件	汽车内饰再生POE	看气味与耐候	高可靠件别用
耐低温容器	再生POE	低温柔韧	普通料别用
发泡缓冲	发泡级再生POE	看发泡性	交联料别用
光伏封装	谨慎评估	需光伏级认证	普通再生别碰

新东西也有边角料，再生POE的故事才刚刚开头，懂行的人早就在偷偷捡这个便宜了。

Three years ago, to save on material costs, I picked out crispy recycled materials; Three years later, I stacked the return slips and repaid the money and interest I had saved, even building the customer's trust. Owners who make turnover boxes and automotive interiors have calculated this kind of account a lot. Today, I'm going to talk about recycled POE, which is a special "medicine" to untie this deadlock. How and where to use this medicine will be explained all at once.

First, let's get to know the main character. POE, scientifically called polyolefin elastomer, is an elastomer formed by metallocene catalysis by copolymerizing ethylene with α-olefins like octene and butene. The surface is pure white, like a soft candy—easy to squeeze and stretch. It has a nickname called the "universal toughening agent"—it's not a hard structural material itself, but you can mix a little into PP or PE, making the brittle material less brittle, with several levels of drop and impact resistance. It is also resistant to low temperatures, weather, and is naturally compatible with polyolefins. Ningbo Kelon New Materials Co., Ltd. supplies plastic raw materials, integrating industry and trade, with common recycled plastic categories stocked year-round. POE is a relatively new and low-key one.

Recycled POE is a new category, so new that most people haven't heard of it yet. Its recycled source is very special: mainly not old shoe soles or old pipes, but scraps cut from photovoltaic film factories. The film used to seal photovoltaic modules and cells now widely uses POE (especially N-type cells), which are cut according to module size during production, leaving a pile of leftover edge strips. These materials are clean, weather-resistant, and fresh off the production line, and after recycling and pelletizing, their performance remains good. When Ningbo Kelon New Materials Co., Ltd. buys these materials, they focus on photovoltaic film scraps as their source, avoiding miscellaneous materials with unclear origins.

POE not for the main material, but as a "medicine"

Many people think POE can be used for injection molding, box or shell. But that's not the case. The correct way to open POE is as a "medicine"—the amount doesn't need to be large, just add 10% to 30% to the brittle PP or PE recycled material, and the impact resistance will quickly increase.

PP repeated processing of recycled materials, molecular chains break, and the biggest fear in making turnover boxes or strapping tapes is dropping—they crack at the slightest drop. Adding calcium powder and fillers only makes the process more brittle. At this point, adding a bit of fat-dissolving POE is like adding a layer of soft tendon to the brittle frame, making it hard to break with each drop or break. Industry data shows that adding between 10% and 30% POE in PP can increase impact strength several times over. But note, it's medicine, not food: too much reduces the material's tensile strength and costs go up. This is the reason why POE "saves a lot by adding a little"—its value isn't in how many pieces you make yourself, but in helping other materials produce fewer defective products.

So the first understanding of recycled POE is: don't compare it to the main material price per ton; use it as the cost of toughening to calculate it. You're not buying a bunch of POE pellets; you're buying the key to "turning brittle recycled material into qualified material." Once you understand this, it's clear why recycled POE is low-key yet valuable.

So why can POE become tougher? It's because of its "dual-phase" capability. In the POE molecular chain, the hard crystalline segment acts like a skeleton, while the amorphous soft segment is like rubber. When mixed into PP or PE, the soft segment disperses into tiny particles. When impacted, these soft particles absorb energy and block crack propagation, essentially equipping the brittle material with countless miniature shock absorbers. Moreover, POE and PP/PE are polyolefins and naturally have good compatibility, so they can be blended together without many compatibilizers, which is why they are more effective than other toughening agents. The key to choosing POE is the melt index (flowability), which matches the substrate; otherwise, mixing it will float on the surface and disperse unevenly, making toughening just superficial.

Besides making toughening agents, POE itself is also a versatile expert. Car bumpers, interiors, and low-temperature resistant containers all love to use it; For wires and cables with soft, flexible protective covers at low temperatures, use it; TPO waterproof membranes and shoe foam also have its presence. When transparent, its light transmittance exceeds 90% and has low haze, which is why photovoltaics choose it for encapsulation films. Recycled POE follows these applications: clean scraps are used for modification, soft parts, and foaming—all of which are natural. It's called "low-key" because it always hides behind the main material as a supporting role, but without it, a bunch of brittle materials and films are hard to produce.

That's also why recycled POE isn't so high-profile on the market: it's neither a general-purpose material that wins by quantity, nor a well-known old material. Its customers are factories doing modification, recycling boxes, and automotive interiors, knowing that adding a little can revive brittle recycled materials. Outsiders see it as ordinary, but insiders secretly use it to control costs and yield. For factories aiming to continue cutting costs in 2026, this kind of category that "others haven't yet reacted to" is often the real lucrative part.

Figure 1 Photovoltaic modules, films, and POE pellets

Behind photovoltaic scraps lies most of the recycled POE

Where does recycled POE come from? This question itself has a story. Unlike PP, it doesn't come from thousands of households' waste products; its assets are mainly in the workshops of photovoltaic factories.

Photovoltaic modules seal the cells between two pieces of glass. The middle layer of adhesive film used to be mostly EVA, but now high-efficiency cells like N-type TOPCon and HJT prefer POE film—because POE has low water vapor permeability, good electrical insulation, resists potential induced decay, and is resistant to moisture and heat aging. It can be stored outdoors for 20 to 30 years and has a longer lifespan than EVA. When film factories mass-produce, the wide film is cut into module sizes, and the cut edges, recoil scraps, and test machine materials are all clean POE, with almost no impurities. These scraps are specially recycled and pelletized, becoming the main source of recycled POE pellets on the market. The industry has long had dedicated teams to collect POE and EVA edge strips from photovoltaic factories, and this is the business.

This also explains another characteristic of recycled POE: it's clean, but not large in quantity and concentrated in sources. Because it's not widely collected from post-consumer waste, but rather follows the expansion of the photovoltaic industry—the more photovoltaic film produces, the more scraps there are. The standard recycling method is: separate photovoltaic edge strips by material (don't mix POE and EVA), crush, clean, and pelletize, then grade them by fat dissolution and use. POE scraps from shoe materials, automotive interiors, and film factories are also supplementary sources. The following grading table is based on source and use.

Why are photovoltaic edge strips so valuable? First, they're clean—the film factory has just cut them off, with no soil or mixed materials; Second, weather resistance. POE is designed for outdoor use for 20 to 30 years, UV resistance, moisture and heat resistance, and this base remains even after regeneration; Third, the source is concentrated, following photovoltaic factories for stable volume. Of course, there are also considerations: POE and EVA are often placed together in photovoltaic edge strips, and PET composite edges must be separated during sorting; mixing them causes depreciation. So even so, the photovoltaic film edge material can be separated from the POE single-material and the mixed one, resulting in a different price and grade.

Grade	Main Sources	Key Indicators	Typical Uses
Photovoltaic Film Edge Scrap Recycled POE	Photovoltaic POE Film Cutting Residue	Clean, weather-resistant, low moisture, good transparency	Toughened modification, transparent products, photovoltaic secondary materials
Toughened grade recycled POE	Factory sprue and film edge granulation	Compatible with PP/PE, improves impact resistance	PP/PE toughening, turnover boxes, packing straps
Automotive interior recycled POE	Car interior trim scraps	Low temperature flexibility, good hand feel	Car interior, soft components
Foaming Grade Recycled POE	Soft parts, shoe material scraps	Can be foamed, good elasticity	Foaming, cushioning, footwear materials
Blown film grade recycled POE	POE film scraps	Transparent, good machinability	Blown film, packaging
General-purpose blended recycled POE	Multi-source hybrid granulation	Performance fluctuates significantly	Low-grade modification and filler blending

Explanation: POE is a relatively new category of polyolefin elastomers. Currently, recycling mainly refers to GB/T 40006.1 "Plastics—Recycled Plastics—Part 1: General Rules" and the corporate standards of various manufacturers. Photovoltaic film edge scraps are the main source of recycled POE. The indicators in the table are summarized from publicly available industry information and manufacturers' technical data. For more grades and physical property parameters, please refer to the manufacturer's official TDS.

Adding a little POE saves more than replacing the entire batch of material.

The cost-reduction logic of recycled POE is really different from other recycled materials. It doesn't ask you to replace the main material entirely; instead, it lets you 'add a pinch' to brittle recycled material. The amount is small, but it can improve the overall yield of the material. That's how the calculation should be done.

You can also see from the market and industry why POE is 'new.' POE has long been monopolized by several international major manufacturers, and the price is not low. It was only in recent years that domestic production breakthroughs have been gradually achieved. Because it is expensive and in high demand, the offcuts from the expansion of photovoltaic films are even more valuable—after these clean POE leftovers are recycled and pelletized, their price is more reasonable than virgin material, and their toughening effect is not bad. Naturally, they have become the low-key, cost-reducing materials that modification plants compete for. Unlike PP or ABS, which everyone is recycling, few people know about it, and even fewer know how to use it properly, which instead leaves cost-saving space for the factories that get in first.

Cost item	New POE	Recycled POE	Difference Explanation
Price per ton of material	Higher	a bit lower	Recycling photovoltaic scraps has a price advantage
Toughening efficiency	Stable	Scraps from the same source are acceptable	Fluctuation in the toughening effect of impurities
Compatibility	Good with PP/PE	The same-source material is highly compatible.	Debris may affect the surface
Weather-resistant and low-temperature resistant	Good	Photovoltaic-grade scrap has good weather resistance	General material has average weather resistance
Mixing ratio	Precision Add	Try in small steps according to the effect	Adding too much will cause it to stretch and fall.
Comprehensive cost	Benchmark	Adding a little saves	Excessive amounts instead reduce intensity and increase cost

Taking this account into consideration, the boundary list below helps you determine where POE should be mixed in and where it shouldn't.

Suitable for using recycled POE: toughening modification of PP/PE regrind; turnover boxes, strapping, automotive interior impact resistance; low-temperature resistance, foam cushioning components.

Photovoltaic module encapsulation: It requires extremely high weather resistance, light transmittance, and reliability. Do not use ordinary recycled POE directly; make sure it is photovoltaic grade.

Don't add too much: adding too much POE will reduce tensile strength. Start with small proportions and increase gradually to find the balance between impact resistance and strength.

Filter impurities first: If the impurities in the recycled material are not thoroughly filtered, even the best POE cannot save the toughness.

High-end optics and highly reliable components: you need to be cautious when using regular recycled POE; new material is more reliable.

One final reminder: Toughening with POE is a 'ratio matter,' not 'the more you add, the better.' Before placing an order, first make a small batch sample and tell the supplier about the regrind you have, the impact resistance level you want, and the existing process temperature so that they can help you determine the model and dosage of POE. Make sure the melt index is correct, impurities are filtered, and the dosage has been tested; only by handling these three things well can recycled POE really help you reduce costs without causing problems.

The secret of why turnover boxes don't crack lies in that small handful of granules

This matter is not new in the turnover box circle. Ningbo Kolon New Materials Co., Ltd. has dealt with many turnover box materials in this line of work. According to a typical scenario example, the names of people and factories have been anonymized.

There is a factory in East China that makes turnover boxes, using recycled PP material to make the boxes, keeping costs very low. However, customers have reported that in winter, the boxes crack easily when dropped, and the edges are full of white marks. The boss has considered adding new PP or fillers; adding new material wouldn't reduce the cost, and adding fillers would make them even more brittle, so they were stuck on what to do for quite a while.

Later, he approached Cologne New Materials. Cologne New Materials looked at his material and first said, don't rush to change the main material—the problem isn't cheap material, it's brittleness. The suggestion is: first filter out impurities from the return material, then add a bit of toughening-grade recycled POE, start with a small proportion and test upward, watching for drops and low-temperature impact. Choose POE models that are compatible with PP and have good fat dissolving effects, and stop when the ratio is sufficiently shock-resistant, stretchable, and doesn't collapse. This way, the main material is still cheap recycled material, and you only spend a small extra amount on toughening agent, so the box won't crack.

Colonew Materials also reminded him that toughening should be tested gradually: start with 10%, see how it performs in low-temperature impact tests; if it's not enough, add more, and stop once the impact resistance is sufficient. Adding too much POE will prevent the box from cracking, but the surface will become soft, dimensions may deviate, tensile strength will decrease, and costs will rise. In addition, dust and metal scraps in the recycled material must be thoroughly filtered out; if impurities are mixed in, even the best POE cannot compensate for those defects. The melt flow index of this batch also needs to match the existing production line; if the melt flow index is too far off, dispersion will be uneven, resulting in boxes with inconsistent hardness.

After trying it out, complaints about the boxes cracking have noticeably decreased, and the cost is much lower than completely replacing with new PP. POE, though not used in large amounts, acts like a shock absorber for brittle materials. This is also why Ningbo Cologne New Materials Co., Ltd., when promoting recycled POE, usually first looks at where your material is brittle and then adjusts the toughening ratio—it is meant to modify the structure, not just to increase tonnage or go through the motions.

Now this factory has already treated recycled POE as a part of the regular formula, testing each batch of recycled material for brittleness first, and then deciding how much to mix in. Looking back, the problem with the boxes that cracked at the time was never that the recycled material was cheap, but that they lacked the small amount of elastomer that would restore the toughness.

POE toughening, adding too much is another matter

After laying out so much background, it all comes down to a single table in the end—just follow it and you won't go wrong. Regenerative POE is a low-key player; if used in the right place, it delivers great efficiency with minimal effort, but if used in the wrong place, it wastes money and reduces performance, so you really need to follow the table.

Application scenario	Recommendation Level	Precautions	When not to use
PP/PE Toughening	Toughened Grade Recycled POE	Mix 10%-30% in small steps for testing	Excessive attention to stretching
Turnover box/packing strap impact resistance	Toughened Grade Recycled POE	First filter out the impurities	Do not use miscellaneous materials
Automotive interior soft parts	Automotive interior recycled POE	Check smell and weather resistance	Do not use for high-reliability parts
Low-temperature resistant container	Recycled POE	Low temperature flexibility	Do not use ordinary materials
Foam cushioning	Foaming Grade Recycled POE	Check foaming	Do not use crosslinking material
Photovoltaic Encapsulation	Assess carefully	Requires photovoltaic-grade certification	Do not touch ordinary regeneration

Even new things have scraps, and the story of recycled POE is just beginning. Those who know the industry have long been secretly taking advantage of this bargain.

Recycled POE, a low-key toughening and cost-reducing material

Ningbo Kolon New Materials Co., Ltd. has long been supplying recycled POE materials, covering different grades and types, and is applied in scenarios such as photovoltaic film scrap recycling, elastomer toughening modification, and PP/PE impact modification. What cost-saving opportunities are hidden in photovoltaic film scraps? How should the blending ratio be determined? Stop forcing brittle materials.
