Plastics That Conduct Heat 导热塑料 上海北京顺德(翻译和整理) 文章来自于塑料产业论坛（） 英文原载plastics technology（2001年6月号） （上海北京顺德email：jiazhiliao@263.net；手 Helping electronics, lighting, and car engines keep cool are some new roles for hermoplastics that are formulated to replace metal or ceramic.热塑性共混塑料的一些新的作用是帮助电子、照明设备和汽车引擎降低温度，从而取代金属和陶瓷。 Heat sinks and other heat-removal applications are among the last areas where thermoplastics—inherent thermal insulators—have yet to replace metals. Until fairly recently, that is. Modifying plastics to improve their thermal conductivity is a burgeoning area of opportunity for a handful of compounders. They have taken up the challenge of using plastics to solve problems of heat build-up in electronics, appliances, lighting, automotive, and industrial products. 散热和别的热量消除应用成为热塑性塑料的必威体育精装版领域，热塑性塑料本来是绝热材料，现在已经替代金属了。直到最近，情况才变得这样。通过塑料改性来改进塑料导热率对于许多共混商是一个充满机会的新兴领域。他们迎接挑战，使用塑料解决电子、电器、照明、汽车和工业产品上的热沉积问题。 Among the pioneers, whose heat-conductive compounds have gone commercial in just the last couple of years, are PolyOne Corp., Cool Polymers, LNP Engineering Plastics, RTP Co., and Ticona Corp. GE Plastics, DuPont, and A. Schulman have development programs under way. And last month, PolyOne entered into a joint-development agreement with Cool Polymers in order to utilize the latter’s capabilities in tool design, thermal-management testing, and injection molding of prototype applications. 最近几年将导热塑料工业化了的领头羊包括Polyone、Cool Polymers、LNP Engineering Plastics、RTP Co. 和Ticona Corp。GE Plastics、DuPont 和A. Schulman的开发计划都在实施中。上个月，PolyOne开始签署与Cool Polymers联合开发的协议，以利用Cool Polymers的模具设计、热管理测试和原型应用的注射模塑方面的能力。 Thermally conductive compounds are generally not considered to be direct drop-in replacements for metals. Instead, they open up a broad range of new opportunities for “thermal management” applications. Parts molded out of this new generation of materials can replace metals and ceramics in some applications, and non-conductive plastics in others. Uses include custom-mold
