PBT 5630--is a 30% glass fiber reinforced halogen free flameretardant injection molding grade
PBT is a unique semi-crystalline high-density polybutyleneterephthalate PBT engineering material. It combines the inherentcharacteristics of PBT with the advantages of high-grade mineralreinforcement. This combination makes it balanced in mechanical,thermal and electrical properties, and has a wide range of chemicalresistance, low water absorption and dimensional stability. Thesolid material has the characteristics of smooth, Satin decorationand heavy weight, similar to the appearance and high-quality handleof ceramics. At the same time, it also has the characteristics ofEngineering thermoplastics: flexible design, easy injectionprocessing, recyclable. After mineral filling and fiberglassfilling, PBT resin can obtain several basic colors. Processors canobtain special design and product appearance by adding specialeffect pigments
PBT 5630特性：玻璃纤维增强材料, 30% 抗溶解性 良好的成型性能 良好的电气性能 耐化学性良好 耐磨损性良好耐气候影响性能良好 耐油 耐油性能 无卤
The research of PBT polymer began in 1982, with trial productionin Shanghai Polyester Factory, 50 t/a pilot test in collaborationwith Wusong Chemical Plant and 400 t/a pilot test in BeijingChemical Research Institute. The capacity of the production unit isnot more than 1000t at best, and the consumption is not much.However, with the development of national economy and the increaseof market demand, the PBT production capacity in China hasincreased rapidly. In 1994, the 5000t/a continuous process (DMTroute) PBT resin production plant of Nantong Synthetic MaterialPlant was built and put into operation, becoming the firstcontinuous ester exchange PBT resin production plant in Asia.
