Celanese CoolPoly® D5112 Thermally Conductive Polyphenylene Sulfide
Categories:	Polymer; Thermoplastic; Polyphenylene Sulfide (PPS)
Material Notes:	CoolPoly D 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 D series is electrically non-conductive and can be used for its dielectric properties. CoolPoly D5112 is a thermally conductive injection molding resin based on a polyphenylene sulfide (PPS) matrix. CoolPoly D5112 is electrically insulative. Thermally conductive polymers like CoolPoly D5112 cool faster than standard injection molding grade resins. Information provided by Cool Polymers, Inc. Celanese acquired Cool Polymers in 2014.
