Ultradur thermoplastic polyester from BASF is a partly crystalline, thermoplastic polyester based on polybutylene terephthalate (PBT). It is used as a material for high-quality, highly stressed engineering parts in a wide variety of industrial sectors. Ultradur thermoplastic polyester features high stiffness and strength, very good dimensional stability at high temperatures, low water absorption, good resistance to many chemicals, and outstanding heat aging performance.
