Description

PI (Polyimide), is an imidized material with a continuous use temperature range of up to 580° F (304° C). It is categorized as an extreme performance material, and offers excellent heat resistance, lubricity, dimensional stability, and chemical resistance.

Polyimide is ideal for environments that must endure extreme temperatures, and provide durability while reducing weight. Polyimide material is lightweight, flexible, and relatively easy to machine. It does not produce significant outgassing even at high temperatures. PI is a better price value for applications that require higher temp ratings than PAI and do not require the extraordinary heat requirements of PBI.
