PI(Polyimide)-General Engineering Plastics

PI(Polyimide)

1. Description

Polyimide (sometimes abbreviated PI) is a polymer of imide monomers. Polyimides have been in mass production. Guangzhou Engineering Plastics Industries (Group) Company has studied and applied this material in many industries for many years. With their high temperature resistance, chemical resistance, mechanical toughness, natural lubricity, wear-resistance & insulation properties. It provides operating temperatures from cryogenic to 300°C (570°F), great plasma resistance, plus a UL rating for minimal electrical and thermal conductivity.
