COOLPOLY® Thermally Conductive Plastics

Engineering plastics are typically good thermal insulators. While this attribute is beneficial in certain applications, it limits the utility of plastics in many heat-generating applications, causing hot spots and increasing device temperatures. Engineers are increasingly demanding material solutions that allow increased power output in smaller spaces, necessitating materials with thermal conductivity.

Imparting thermal conductivity to plastics changes the way a part responds to heat. Thermally conductive plastics manage thermal energy rather than merely surviving it. This property enables plastics to meet demanding engineering requirements more cost-effectively than metals, ceramics, and other materials. Thermal conductivity was a “missing property” from plastics.
