Polybutylene Terephthalate (PBT)

Polybutylene terephthalate (PBT) engineering resin is high molecular weight, high performance material used for a wide range of applications in automotive, electrical and electronic, appliance, and industrial equipment applications.

PBT is often used in mineral or glass filled grades. Their high crystallinity and low melt viscosity means that they are ideally suited for injection moulding complex parts which require high strength, good dimensional stability, and insulation properties. Therefore, PBT is used in connectors, switches, relays, bobbins and sockets where they have displaced the traditional thermoset moulding compounds.
