Description

It is a specially designed long-chain polyphthalamide (PPA) that combines a low water absorption and excellent mechanical properties over a broad temperature range. Depending on the grade the key features are: Mechanical properties at high temperature, low water absorption, outstanding fuel barrier, heat resistance, a low friction coefficient, Low wear, chemical resistance, long term heat resistance, high reflectivity, less color change by heat and light, high flowability
