Polyester is a general term for polymers obtained by polycondensation of polyhydric alcohols and polybasic acids, and is an engineering plastic with excellent electrical insulation performance. Polycarbonate (PC for short) is a high molecular polymer containing carbonate groups in the molecular chain. According to the structure of ester groups, it can be divided into aliphatic, aromatic, aliphatic-aromatic and other types. Polyethylene terephthalate (PET) is a highly crystalline polymer and an engineering plastic with excellent properties. Its surface is smooth and shiny, has excellent physical and mechanical properties in a wide temperature range, long-term use temperature can reach 120 ℃, excellent electrical insulation, high frequency electrical properties are still excellent, creep resistance, fatigue resistance, friction resistance, dimensional stability is very good. Polybutylene terephthalate (PBT) has very good chemical stability, mechanical strength, electrical insulation properties, thermal stability and very low hygroscopicity. Sunrise modified PBT engineering plastics, with high strength, hardness, toughness, heat resistance, friction resistance, excellent surface effect and good tinting strength; at the same time has excellent electrical insulation properties and high CTI index, and at a lower temperature has excellent fluidity, can effectively shorten the molding time. The company's modified polyester PC/PET/PBT series includes flame retardant, reinforced, alloy and other modified products, with excellent electrical and mechanical properties, long-term fatigue resistance and thermal stability, widely used in automotive electronics, household appliances, electronic appliances and other fields.
