HONYPLAS®PI poyimide material (chemical name is polyimide), Polyimide Sheet, Vespel SP-1 equivalent its standard semi-finished products include three forms of plate, bar and tube, all of which can be used for machining. In addition to the production of semi-finished profiles by compression molding, the direct molding process can also be used to mass-produce finished components, which is cost-effective.
HONYPLAS®PI Polyimide plastic is a non-melting high temperature plastic. It still has high strength, excellent dimensional stability and creep resistance above 260°C. It has low wear rate, high pV rate and can work under unlubricated conditions, so it is an ideal material for challenging friction and wear applications, which can significantly extend the service life of the application and reduce maintenance costs. High purity and low gas permeability also make it very suitable for vacuum, aviation and semiconductor industry applications.
