Polybutylene terephthalate (PBT) is an engineering plastic with excellent properties. It has excellent toughness and fatigue resistance, heat resistance, weather resistance, good electrical properties and low water absorption. Strengthening and flame retardant modification of PBT can significantly improve the heat resistance, modulus, dimensional stability and flame retardancy of PBT. The modified PBT products are widely used in automotive, electronic and electrical industries
