PESU - Polyethersulfone

Polyethersulfone (PESU), is a high-performance material with a temperature profile that is unique among engineering thermoplastics a long-term temperature resistance up to 180°C.

PESU is used in apparatus engineering and in the electrical and electronics fields in the automotive and transportation sectors, in the food and household sectors as a substitute for glass, metal, ceramic, and porcelain.
