Polybutylene terephthalate (PBT) is an engineering polymer which is thermoplastic in nature and is used in electronics and electrical industriesas an insulator. It is a type of polyester and a thermoplastic (semi-crystalline polymer). PBT is solvent resistant, is mechanically strong, slightly shrinks during forming and is heat-resistant up to a temperature of 150 °C (or 200 °C with glass-fiber strengthening). It can be made noncombustible when treated with flame retardants.Polybutylene ... Read more
