PBT

Polybutylene terephthalate (PBT) is a thermoplastic engineering polymer that can be used as an insulator in electrical or electronic products. It is commonly used for insulation in residential electrical work and for plug connectors in automobile manufacturing. In everyday household products, it may be selected for showerhead or iron handles. PBT can also be spun into fibers and used to make bristles for toothbrushes or cosmetic brushes.
