Celanese CoolPoly® E5101 Thermally Conductive Polyphenylene Sulfide
Categories:	Polymer; Thermoplastic; Polyphenylene Sulfide (PPS)
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 E5101 is a thermally conductive injection molding resin based on a polyphenylene sulfide (PPS) matrix. CoolPoly E5101 is electrically conductive. Thermally conductive polymers like CoolPoly E5101 cool faster than standard injection molding grade resins. Information provided by Cool Polymers, Inc. Celanese acquired Cool Polymers in 2014.
