PBT (polybutylene terephthalate) is widely used due to its high rigidity and strength, as well as its good friction and wear properties. It is resistant to many solvents and performs well at operating temperatures between – °C and up to 150 °C. Because it cools more favorably than PET, PBT is particularly well suited for injection molding and is preferably used for precision mechanical components in device construction. Typical applications include housings for electrical devices, electrical connectors, and various household items. In addition, PBT serves as an alternative to polyacetal (POM).
