Celanese CoolPoly® E8101 Thermally Conductive Thermoplastic Elastomer
Categories:	Polymer; Thermoplastic; Elastomer, TPE
Material Notes:	CoolPoly E series of thermally conductive plastics transfers heat, a characteristic previously unavailable in injection molding grade polymers. CoolPoly is lightweight, netshape moldable and allows design freedom in applications previously restricted to metals. The E series is electrically conductive and provides inherent EMI/RFI shielding characteristics. CoolPoly E8101 is a thermally conductive injection molding resin based on a thermoplastic elastomer (TPE) matrix. CoolPoly E8101 is electrically insulative. Thermally conductive polymers like CoolPoly E8101 cool faster than standard injection molding grade resins. Information provided by Cool Polymers, Inc. Celanese acquired Cool Polymers in 2014.
