科思创首次推出90%再生含量的聚碳酸酯
Covestro Debuts Polycarbonate with 90% Recycled Content
这种新材料的碳足迹比传统的原始树脂小70%，但可用于要求高饱和的颜色和阻燃应用。
The carbon footprint of the new material is 70% smaller than conventional virgin resin, yet can be used in demanding highly saturated color and flame-retardant applications.

随着各行业加大力度追求循环性和气候中性，市场对高含量消费后回收（PCR）材料的需求正在迅速增长。然而，保持与原始树脂同等的性能和质量仍然是一个常见的挑战。
Market demand for high-content post-consumer recycled (PCR) material is growing rapidly as industries step up efforts in pursuit of circularity and climate neutrality. Retaining performance and quality on a par with virgin resin, however, remains a common challenge.
实现90%的PCR含量聚碳酸酯（PC）需要高质量的PCR原料和稳健的配方工艺，材料供应商科思创声称其模克隆PCR PC树脂已经实现了这一点，该树脂目前可供亚洲的成型商使用。作为科思创CQ循环解决方案组合的一部分，新型PC树脂的碳足迹比类似的化石原生塑料低70%。
Achieving a 90% PCR content polycarbonate (PC) requires both high-quality PCR feedstock and a robust formulation process, something that materials supplier Covestro claims to have achieved with its Makrolon PCR PC resin that is currently available to molders in Asia. The carbon footprint of the new PC resin, part of the CQ portfolio of circular solutions at Covestro, is 70% lower than that of a comparable fossil-based virgin plastic.

科思创于2023年12月在其位于上海的综合工厂开始运营其首条PC专用机械回收复合线。该生产线每年将生产25000多吨优质PC和含有机械回收材料的混合物。
Covestrocommenced operationsat its first dedicated mechanical recycling compounding line for PC at its integrated site in Shanghai in December 2023. This line is set to produce more than 25,000 tonnes annually of premium-grade PC and blends containing mechanically recycled materials.
工程塑料部门全球负责人Lily Wang在最近于上海举行的Chinaplas展会上接受PlasticsToday采访时表示，科思创承诺到2026年，每年在亚太地区供应超过60000吨可回收PC。她指出：“随着需求的增长，我们在上海现有的复合能力随时可以转向机械回收。”
Covestro is committed to supplying more than 60,000 tonnes of recycled-content PC annually in the Asia Pacific region by 2026, according to Lily Wang, global head of the engineering plastics segment, who spoke with PlasticsToday at the recent Chinaplas show in Shanghai. “Our existing compounding capacity in Shanghai can always be made available to shift to mechanical recycling as demand grows,” she noted.
汽车、E&E和消费品增长
Auto, E&E, and consumer products growth
对PCR塑料的需求正在增长，特别是在电气和电子（E&E）产品、汽车和消费品行业的应用中。使PCR含量PC对这些市场特别有吸引力的是它能够实现非凡的白度和高度饱和的颜色，这对于具有高回收含量的PCR塑料来说通常是一个挑战。这是通过在复合过程中选择高质量的可回收物并优化材料组成而实现的。PCR级采用无卤阻燃剂制造，在不增加环境影响的情况下满足性能要求。它还符合最高的UL 94 V-0可燃性等级。
Demand for PCR plastics is growing, particularly in applications within the electrical and electronic (E&E) products, automotive, and consumer goods sectors. What makes the PCR-content PC particularly attractive to these markets is the ability to achieve exceptional whiteness and highly saturated colors, which is typically a challenge for PCR plastics with high recycled content. This is made possible by selecting high-quality recyclates and optimizing the material composition during the compounding process. The PCR grade is manufactured with halogen-free flame retardants that meet performance requirements without increasing the environmental impact. It also meets the highest UL 94 V-0 rating for flammability.
与Jabra的合作
Partnership with Jabra
Covestro的Bayblend FR3010 R75 PC/丙烯腈-丁二烯-苯乙烯（ABS）混合物是商业级混合物的一个例子，其包含回收含量，在这种情况下为总含量的75%。丹麦品牌Jabra最新的Evolve2耳机系列用于音频设备和视频会议系统的耳罩采用了这种材料。该公司表示，与传统的化石燃料相比，其碳足迹降低了50%，但仍符合性能要求。
Covestro's Bayblend FR3010 R75 PC/acrylonitrile-butadiene-styrene (ABS) blend is one example of a commercial grade that incorporates recycled content, in this case 75% of overall content. The ear cups of Danish brand Jabra's latest Evolve2 headset series for audio equipment and video conferencing systems employ this material. The company said it achieves a 50% lower carbon footprint compared to its conventional fossil-based counterpart, but still meets performance requirements.
