PBT polymerization varieties£º

PBT is polybutylene terephthalate. Can be derived from PTA and butanediol polymerization. Condensation by-product of oxygen for four furan. PTA used directly esterification France transesterification lower production costs, without recovery of methanol. At present continuous synthesis of PBT resin alloy technology is the main direction of development. In PBT varieties, often need to enhance fire-retardant, anti-hydrolysis, such as additional performance, or blends can be modified copolymer to achieve function.

PBT is a thermoplastic engineering plastics, with high wear-resistance, heat resistance, mechanical strength, insulation, anti-aging, such as water resistance of the excellent performance, easy molding processing. Its modified products normally used for electronics and electrical industries.
