Ultradur is BASFs brand name for its line of partially crystalline, thermoplastic, saturated polyesters derived from
polybutylene terephthalate (PBT). They are employed as materials for high-quality technical components in many industry sectors.

Ultradur shows its strengths wherever high-quality and above all heavy-duty parts are required â?? for example in the automotive industry, in the electrics and electronic sectors. The range of applications which benefit from these properties of Ultradur in both industry and everyday life is vast. A feature that is particularly important is the low water absorption and thus the fact that the mechanical and electrical properties are largely independent of the moisture content or the climatic surrounding conditions. Particularly for components that are safety-relevant and have to work reliably for the entire lifetime of a component,Ultradur is indispensable.
