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

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%. Thanks 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,
semicrystalline 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
