Polybutylene Terephthalate (PBT)

PBT (Polybutylene Terephthalate) is a thermoplastic crystalline polymer which is mechanically strong, solvent resistant and has low shrinkage properties during formation. PBT is also heat resistant up to 150°C (or 200°C if it is reinforced with glass fibre). It can be treated with flame retardants to make it noncombustible.
