Evonik Develops New Metal-replacing, High-temperature PPA Base Polymer

Published on 2018-01-05. Author : SpecialChem

Evonik has developed a new base polymer for the plastics industry. VESTAMID® HTplus TGP3717 is distinguished by stable mechanical properties at sustained high temperatures.

High-temperature Polymer


The new high-temperature polymer can withstand mechanical stress up to 135°C; the glass transition temperature is 155°C. While the modulus of elasticity of a standard product falls by approximately 80% at 120°C, the decrease for Evonik’s new base polymer is only 15%.

Due to its high crystallinity, the new plastic material has the properties typical of the VESTAMID® HTplus product range such as very good chemical resistance and dimensional stability and simple processing.

High-performance Polymer as a Replacement for Metals


VESTAMID® HTplus from Evonik has been specially developed as a substitute for metal in classic metal applications such as highly filled molding compounds. The high-temperature stable, semi-crystalline material is based on polyphthalamide (PPA).

Evonik has more than 50 years of experience in the development and production of high-performance polymers. Its extensive product portfolio covers solutions for almost every industrial application.
