Polybutylene terephthalate (PBT)

Polybutylene terephthalate (PBT) is an engineering plastic for industrial applications where dimensional stability, electrical insulation, and chemical resistance are important. The material is widely used in the automotive, electrical engineering, electronics, and mechanical engineering industries, including for connectors, housings, switches, and precision parts.

PBT combines high stiffness with good wear resistance and low moisture absorption. As a result, parts remain dimensionally stable and function reliably, even under varying environmental conditions. In addition, this plastic offers good thermal properties, a good surface quality, and efficient processability in injection molding processes.

For B2B buyers and technical decision-makers, PBT is a logical choice when a plastic is required that combines performance and process reliability. Polybutylene terephthalate is available in various grades, including glass fiber-reinforced variants, for applications involving higher mechanical loads or extra-dimensional stability.
