老高在东莞做特种工业件，一批PC/HIPS定制合金料因为设备升级，在仓里压了五吨多。这料是当初找配混厂专门定制的，袋子上只有内部编号，连个通用牌号都查不到。设备一换，新设备跑的是别的体系，这五吨料瞬间成了"知道是好料却不知道卖给谁"的死库存。他打电话问原来的配混厂能不能退，对方一句"定制料不退不换"，把他堵得没话说。
PC/HIPS这种定制合金，呆滞起来连出处都找不到。
定制料的好处是合身，坏处是不合身那天，谁都接不住。
PC/HIPS为什么难处理？它把PC的强度和HIPS的易成型拼在一起，专门给一些对成本敏感、又要一定强度的工业件用。可正因为是定制配混，每家厂的PC/HIPS比例都不一样，外观颗粒可能看着差不多，物性却差出一大截。这就像定制西服——你合身的时候是宝贝，胖瘦一变，卖给二手店人家都不敢收。普通回收商拿到手，既不知道你这袋PC占几成，也不知道有没有加阻燃，干脆按"不明合金"压你一刀。定制料单价不低，压在仓里又是资金又是租金，时间一长HIPS那部分还容易吸潮，表面发乌。
定制料就怕的不是放，是没人查得到它的底细。
还有个麻烦：定制料没有公开牌号，连物性表都在原配混厂手里。你想转卖，下家要资料你拿不出，只能靠口头描述，报出来的价自然没底气；遇到较真的，连门都进不去。
再说收废料的。你打一圈电话，对方一听"定制合金、无通用牌号"，先沉默三秒，然后报个价低到地板。统货商碰到没有标签的料，套路你闭着眼都能背：先把你说慌，"这料没牌号，谁知道里面加了啥，我们只能按统货收"，然后一刀砍到脚踝。有些更绝，上门看都不看就压价——反正你也没物性表，他说啥就是啥。说白了，他不是在收货，是在赌你不懂行，赌赢了就捡个大便宜。
没有标签的料，在贩子眼里就是没有价的料。
科隆新材做终端消化型回收，PC/HIPS这种定制合金我们接得动。我们手上长期有做特种工业件、结构件的客户在用各类PC基合金，热门批次收进来当天就能走，不压库。遇到偏门配方、混批或者无标签的，我们拉回厂做物性测试，按实测结果分级，进自家改性配方按比例消化，做到不挑牌号、不挑批次。定价按实测强度、流动性和外观分级，明码实价，不是"没标签就乱砍"。自有产能和固定客户托底，报价稳，不随行情大起大落。
没标签不怕，怕的是没人敢真测。
合作流程五步：报料、分级评估、上门收货、抵扣货款、结算开票。你把料袋外观、数量、当初做什么件用的拍过来，我们按实物定级报价，谈拢就上门拉货。回收款能直接抵你后续采购新料的货款——工程塑料这块我们自有KONICE改性塑料系列。东莞老高那五吨无标签定制料，我们拉回厂测完物性，折了个实在价，直接抵了他下半年KONICE改性料差不多一半的货款，原来那张"不退不换"的采购单，当天就变成了一张新料抵扣单。
把没人认得的料，变成认得下家的料。
可回收的PC/HIPS牌号我们接得不少。LNP、RTP、Avient这类PC/HIPS定制配混料的主流体系，都在常规收货范围；其他厂牌、其他配方、甚至无标签的PC/HIPS，也欢迎报料，具体以实物评估为准。可回收形态包括呆滞原包料（整托散包都行）、水口料和浇口料、工业件边角料和机头料、特种件废品与不良品，以及项目收尾的库存尾料，哪怕标签掉了，只要你说得出当初做什么件，都能谈。
避坑三条。"定制料随便找个收废料的？"真相是没标签更要找能实测的人。"放着等下一个项目用？"真相是项目不等人，料越放越窄。"谁价高卖给谁？"真相是不敢测的贩子，只能给你统货价。
合规这块：正规回收处置，过磅单、回收单齐全，流向可查，能配合过环保审计和ISO审核，绝不流向非法小作坊。
Lao Gao works in Dongguan specializing in industrial parts, and a batch of PC/HIPS custom alloy material was stored in a warehouse due to equipment upgrades. This material was originally specially customized by a mixing factory, with only internal numbers on the bags, and no generic grades to be found. Once the equipment was changed, the new equipment ran on a different system, and those five tons instantly became dead stock of "knowing it's good material but not knowing who to sell it to." He called the original mixing factory to ask if it could be returned, but the reply was, "No return or exchange for custom materials," leaving him speechless. Custom alloys like
PC/HIPS get stuck so stagnant you can't even find their source.
The advantage of custom materials is that they fit well; the downside is that when they don't fit, no one can handle them. Why is
PC/HIPS so hard to handle? It combines the strength of PC with the moldability of HIPS, specifically for cost-sensitive industrial parts that require a certain level of strength. But precisely because it's a custom mix, each factory's PC/HIPS ratio is different. The particles may look similar, but their physical properties differ greatly. It's like a custom suit—when it fits, it's a treasure; once you change weight, even second-hand shops wouldn't dare accept it. Ordinary recyclers get it and don't know what percentage of your PC bag is or if it's flame-retardant, so they just label it a "unknown alloy" and cut you hard. Custom materials are expensive and stored in the warehouse with both capital and rent. Over time, the HIPS part absorbs moisture easily and the surface looks dull.
The real worry about custom materials isn't being listed, but that no one can find out their background.
There's another problem: custom materials don't disclose the grade, and even the physical property chart is held by the original mixing factory. If you want to resell, the next seller can't provide the information, so you can only rely on verbal descriptions, so the quoted price is naturally unreliable; If you get serious, you can't even get inside.
Now let's talk about the scrap collectors. You make a round call, and the other party hears "custom alloy, no common grade," they first stay silent for three seconds, then quote prices as low as the floor. When a wholesaler encounters unlabeled materials, their tricks are so good you can recite them with your eyes closed: first, they tell you, "This material has no grade, who knows what's added? We can only buy as standard," then cut it down to the ankle. Some are even worse, they bargain without even looking—after all, you don't have a physical property chart, so whatever they say goes. To put it bluntly, they're not actually receiving goods; they're gambling that you don't know the trade, and if you win, you get a huge bargain.
Materials without labels are considered worthless materials in the eyes of dealers.
Kelong New Materials does end-use digestion recycling; we can handle custom alloys like PC/HIPS. We have long-term clients who make special industrial and structural parts using various PC-based alloys. Popular batches are picked up and shipped the same day, no inventory pressure. For unconventional formulas, mixed batches, or unlabeled products, we bring them back to the factory for physical property testing, classify based on actual results, and use our own modified formulas for proportional consumption, ensuring no discrimination by grade or batch. Pricing is based on measured strength, flowability, and appearance, with clear and real prices—not "bargaining without labels." Own production capacity and fixed customers provide a bottom line, with stable quotes that don't fluctuate wildly with market trends.
No labels are not afraid; what worries is that no one dares to test for real .
Five-step cooperation process: material reporting, grading evaluation, on-site pickup, deduction of payment, settlement and invoice. You order the appearance and quantity of the material bags, and what they originally used to be made. We grade and quote based on the actual product, and once agreed, we come to the door to deliver the goods. The recycled amount can be directly used to offset your future purchase of new materials—for engineering plastics, we have our own KONICE modified plastic series. For Dongguan Lao Gao's five-ton unlabeled custom materials, we brought them back to the factory for physical properties testing, discounted them to a real price, and directly offset about half of the payment for his KONICE modified materials for the second half of the year. The original "no return, no exchange" purchase order became a new material deduction form that day.
Turning unrecognized materials into materials recognized by the next supplier.
We have received quite a few recyclable PC/HIPS grades. Mainstream systems for PC/HIPS custom blends like LNP, RTP, and Avient are all within the regular acceptance range; Other brands, formulas, and even unlabeled PC/HIPS are also welcome, subject to actual product evaluation. Recyclable forms include obsolete original pack material (whole pallets or loose packages are fine), sprue and gate materials, industrial scrap and machine head scrap, special parts scrap and defective products, and inventory scrap scraps from project closures. Even if the label is missing, as long as you can say what you originally made, you can negotiate.
Three pitfalls to avoid. "Custom parts, just pick any scrap supplier?" The truth is, without labels, you need to find someone who can actually test it. "Leave it for the next project?" The truth is, projects don't wait for people, and the material gets narrower and narrower. "Whoever sells at the highest price?" The truth is, dealers who don't dare to test can only offer you a uniform price.
