Conductive Polycarbonate (CN-P) Specifications

Description

The CN-P material is carbon-powderfilled, while the CN-SS is filled with small non-sloughing stainless steel fibers. Both have high flexural strength and good thermal stability to 275° F. The CN-SS material has excellent impact strength, while the CN-P is UL94 V-0 rated at .030” and is thermoformable in thinner gauges (.010” - .060”).

Applications

Semiconductor/electronic components • Cassette housings • Telecommunications hardware • Explosives handling equipment

Advantages of Conductive Polycarbonate (CN-P)
