(Conductive Acetal Copolymer)) Download Product Brochure (60kb - pdf)

Stainless-steel-fiber-filled, non-sloughing, dimensionally stable material HDT @ 264 psi of 225° F. This material has relatively high chemical resistance, is extremely strong and stiff, and is an excellent choice for situations where carbon-based conductive fillers are not acceptable. Easily machined with carbide-tipped tooling to tight tolerances.

The following physical property information is based on typical values of the resin.
