A class of polymers known as engineering plastics has better mechanical and thermal characteristics than regular plastics.

Most of the PPS used is its modified variety. Glass fiber reinforced PPS is one of them.

The modified polypropylene material reinforced by carbon fiber has a series of advantages, such as light weight, high modulus, high specific strength, low coefficient of thermal expansion, high temperature resistance, heat shock resistance, corrosion resistance, good vibration absorption, etc., and can be applied to auto parts such as automobile sub-instrument assembly.
