Celanese CoolPoly® E2 Thermally Conductive Liquid Crystalline Polymer
Categories: Polymer; Thermoplastic; Liquid Crystal Polymer (LCP)

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 E2 is a thermally conductive injection molding resin based on a liquid crystalline (LCP) matrix. CoolPoly E2 is electrically conductive. Thermally conductive polymers like CoolPoly E2 cool faster than standard injection molding grade resins.

Celanese acquired Cool Polymers in 2014.
