saturated polyesters derived

"Ultradur® is BASF's brand name for a family of partially crystalline, thermoplastic, saturated polyesters derived from polybutylene terephthalate (PBT). They are used as materials for high-quality technical components in many industrial sectors.
Ultradur® demonstrates its advantages wherever high quality and, above all, heavy-duty parts are required – for example in the automotive industry and the electrical and electronics industry. These properties of Ultradur ® have a wide range of applications in industry and daily life. A particularly important feature is the low water absorption, so that the mechanical and electrical properties are largely independent of moisture content or surrounding climatic conditions. Especially for safety-related components that must function reliably throughout their entire service life, Ultradur® is indispensable.
