Polyimide shapes extend part life in sealing and bearing applications

29 July 2011

DuPont has introduced Vespel SCP-5009 polyimide shapes, which are intended to help customers looking for extended part life in many sealing and bearing applications, especially in non-lubricated high-friction environments. Vespel SCP-5009 shapes combine resistance to temperatures above 300°C, high compressive and mechanical strength, broad chemical resistance, and a low coefficient of friction - properties that can result in significantly extended wear life, exceeding that of lubricated metals.

Vespel SCP-5009 shapes are also very easy to machine to near metal-like tolerances from rods or bars. The latest products  provide enhanced strength and dimensional stability — extending the high-temperature capabilities of non-metallic parts — while offering substantial cost, weight and performance opportunities over metals, ceramics and other engineering plastics.
