1. INSTRUCTION
Polybutylene terephthalate (PBT) is a thermoplastic engineering polymer, that is used as an insulator in the electrical and electronics industries. It is a thermoplastic (semi-)crystalline polymer, and a type of polyester. PBT is resistant to solvents, shrinks very little during forming, is mechanically strong, heat-resistant up to **0 °C (or **0 °C with glass-fibrereinforcement) and can be treated with flame retardants to make it noncombustible.
2. ADVANTAGE
PBT is closely related to other thermoplastic polyesters. Compared to PET (polyethylene terephthalate), PBT has slightly lower strength and rigidity, slightly better impact resistance, and a slightly lower glass transition temperature. PBT and PET are sensitive to hot water above *0 °C (**0 °F). PBT and PET need UV protection if used outdoors, and most grades of these polyesters are flammable, although additives can be used to improve both UV and flammability properties.
PBT resin produced by advanced PTA and BDO continual reaction,has characteristics of widw control range of intrinsic viscosity and norrow range of intrinsic viscosity deviation ,low carboxyl end groups value, good color and luster.
