Celanese CoolPoly® E1201 Thermally Conductive Polypropylene
Categories: Polymer; Thermoplastic; Polypropylene (PP)
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 E1201 is a thermally conductive injection molding resin based on a polypropylene matrix. CoolPoly E1201 is electrically conductive. Thermally conductive polymers like CoolPoly E1201 cool faster than standard injection molding grade resins.
