老梁在深圳宝安开了家电子烟壳体注塑厂，专做透明雾化器仓。上个月品牌方把壳体材料从PCTG换成了普通PC，仓库里那两托伊士曼Tritan TX1001、几袋SK T95G，就这么在托盘上躺了快一年。袋子上落了层灰，标签还清楚，可就是没人来提。老梁每次盘点都叹气——这料当年花了大价钱进口，现在堆在那儿跟废塑料没两样。
电子烟行业说变就变，压在仓里的料不会自己跟着变。
呆滞料不是货，是被行业周期遗忘的现金流。
PCTG这东西，透明共聚聚酯，比PETG耐化学、比PC轻，专做母婴水杯、电子烟仓、医疗件。它娇贵在哪？怕吸潮、怕高温、怕跟别的透明聚酯混。跟透明眼镜片放久了磨花一个道理——料本身没坏，可吸了潮，注塑的时候就容易出银纹、发雾。更头疼的是PCTG单价不低，一托压下去就是好几万，放一年资金成本和仓库租金两头吃。
高端透明聚酯一旦吸潮，身价就跟着打折。更头疼的是PCTG跟普通透明聚酯摆一起，光靠眼睛分不出来，得测耐化学性和透光率。贩子不懂这套，抓起来捏两下，直接按透明料统货给你算。
说个真事，老梁之前问过一圈收废料的。一听是PCTG，有人直接说"这共聚聚酯太小众，我们做不了"；有人报了个价，等老梁把人叫过来，对方捏了两下袋子，说"你这料放久了吸潮，只能当普通透明聚酯收"，价格砍下去快三成。老梁想反驳，可人家两手一摊，"你不卖给我，门口排队的人多了去"。
统货商看见小众共聚聚酯，比看见肥肉还开心——他知道你找不到下家，正好往死里压。他不是来收货的，是来收你的焦虑的。
说白了，他给的价，永远是他转手再卖一刀的价。
科隆新材做PCTG回收走终端消化路线。伊士曼Tritan TX1001、TX2001、EX401这种母婴水杯和电子烟常用牌号，下游包装厂一直在用，收进来分级后直接对口走掉。SK Skygreen T95G、T110（T100HG）、JN200、JN100这些化妆品和日品牌号，我们也接——冷门料进自家透明改性配方里消化，不挑批次不挑颜色。PCTG本来就是透明共聚用的，回掺到透明改性料里，物性还搭得上。
定价按透光率、耐化学性、外观分级，干净透亮的出好价，轻微吸潮的按改性透明料收。自有产能和长期客户托底，报价稳，不会因为你料小众就坐地起价。
共聚聚酯不是没人要，是你没找对真正用它的人。
合作流程走五步：报料、分级评估、上门收货、抵扣货款、结算开票。老梁那批料就是这么处理的——他拍了照发来，标了TX1001大概三吨、T95G两吨，我们评估完报了价，约了时间上门过磅。回收款直接抵扣了他下个月采购KONICE改性塑料的货款，抵了差不多两万多。仓库清出半间，老梁说那感觉跟清了笔旧账一样舒坦。
回收不是把共聚聚酯贱卖，是把压在仓位上的死钱盘活。
目前可回收的PCTG牌号，包括伊士曼Tritan TX1001、TX2001、EX401，SK Skygreen T95G、T110（T100HG）、JN200、JN100等主流编号；国产PCTG改性企业等其余牌号以实物评估为准。形态上都收：呆滞原包料、母婴水杯边角、电子烟壳浇口、医疗透明件废品、库存尾料。透明料别跟有色料混堆，分开装分级价更优。
三个常见误区，给你提个醒——
"共聚聚酯吸潮了就是垃圾？"真相是轻微吸潮进改性透明配方照样能用，直接扔了才亏。
"小众透明料没人收？"真相是找对终端，TX1001这种母婴常用料照样走得快。
"先放着再说？"真相是PCTG放久了吸潮发雾，越放越不值钱。
Old Liang opened an e-cigarette shell injection molding factory in Bao'an, Shenzhen, specializing in transparent atomizer warehouses. Last month, the brand replaced the shell material from PCTG to regular PC. The two Toysman Tritan TX1001 and several bags of SK T95G in the warehouse sat on the tray for almost a year. A layer of dust had fallen on the bags, the labels were still clear, but no one came to pick them up. Every time Old Liang did the inventory, he sighed—this material was imported at a high price back then, and now it's piled up there like waste plastic.
The e-cigarette industry changes instantly; the material stored in the silo doesn't change on its own.
Obsolete material isn't goods; it's cash flow forgotten by the industry cycle.
PCTG this thing, transparent copolyester, is more chemically resistant than PETG and lighter than PC, specifically made for mother and baby water cups, e-cigarette holders, and medical devices. What makes it so delicate? It fears moisture absorption, high temperatures, and mixing with other transparent polyesters. It's the same as clear lenses that wear out after being stored for a long time—the material itself isn't bad, but if it absorbs moisture, it tends to develop silver lines and fog during injection molding. What's even more troublesome is that PCTG is expensive—if you press it down, it can cost tens of thousands, and you have to pay for a year of capital and warehouse rent.
High-end transparent polyester gets discounted once it absorbs moisture. What's even more troublesome is that when PCTG is placed together with ordinary transparent polyester, you can't tell just by looking, so you have to test chemical resistance and light transmittance. Dealers don't understand this trick, grab it, squeeze a couple of times, and directly quote it as transparent material for you.
Here's a real story: Old Liang once asked around around waste collectors. When he heard it was PCTG, someone immediately said, "This copolymer polyester is too niche, we can't do it." Someone quoted a price, and when Old Liang called them over, the other party pinched the bag twice and said, "Your material gets damp from sitting too long, so you can only buy it as regular transparent polyester," cutting the price by nearly 30%. Old Liang wanted to argue, but the seller shrugged, "If you don't sell to me, there will be a long line at the door."
The wholesaler was happier seeing niche copolymer polyester than seeing the fat meat—he knew you couldn't find a buyer, so he was pushing it hard. He's not here to collect goods, he's here to collect your anxiety.
To put it bluntly, the price he gives is always the price he would sell at once more.
Cologne New Materials follows a terminal digestion route for PCTG recycling. Eastman's Tritan TX1001, TX2001, EX401, and other commonly used brands for mother-and-baby water cups and e-cigarettes have been used by downstream packaging factories, and after grading, they are directly taken away. SK Skygreen T95G, T110 (T100HG), JN200, JN100 cosmetics and Japanese brand numbers are also accepted — we use niche materials into our own transparent modified formulas for digestion, regardless of batch or color. PCTG is originally used for transparent copolymerization, and when mixed back into transparent modified materials, its physical properties still match.
Pricing is based on light transmittance, chemical resistance, and appearance. Clean and bright materials are priced well, while slightly moisture-absorbing materials are accepted as modified transparent materials. With our own production capacity and long-term customers as a backup, our quotes are stable—no price hikes just because your material is niche.
Copolyester isn't unwanted by anyone; it's just that you haven't found the right people who truly use it.
The five-step cooperation process: material reporting, grading evaluation, on-site pickup, deduction of payment, settlement and invoicing. That's exactly how Lao Liang handled the material—he took photos and sent them, bidding about three tons of TX1001 and two tons of T95G. After we appraised and quoted the price, we arranged a time for on-site weighing. The recycling payment was directly deducted from his purchase of KONICE modified plastic next month, totaling about twenty thousand. After clearing half the warehouse, Lao Liang said it felt as satisfying as clearing old debts.
Recycling isn't about selling copolyester cheaply, but about revitalizing the dead money tied to the warehouse.
Currently, the PCTG grades available for recycling include Eastman Tritan TX1001, TX2001, EX401, SK Skygreen T95G, T110 (T100HG), JN200, JN100, etc.; Domestic PCTG modification companies and other grades are subject to physical appraisal. In terms of form, we collect: obsolete original packaging, mother-and-baby water cup edges, e-cigarette shell gates, medical transparent parts scrap, and inventory scrap. Don't mix transparent materials with colored materials; packing them separately for graded prices is better.
Three common misconceptions, here is a reminder —
"Is copolyester considered trash if it absorbs moisture?" "The truth is, even mild moisture-wicking can still be used in modified transparent formulas; just throw it away and you'll lose money."
"Niche transparent materials no one buys them?" "The truth is, if you find the right terminal, a commonly used material like TX1001 for mothers and babies will still sell quickly."
"Should we just leave it for now?" "The truth is, PCTG absorbs moisture and fogs up for too long, and the more you store it, the less valuable it gets
