PBTCrastin聚对苯二甲酸丁二醇酯，属于聚酯系列，是由1.4-丁二醇1.4-Butylene glycol与对苯二甲酸PTA或者对苯二甲酸酯DMT聚缩合而成，并经由混炼程序制成的乳白色半透明到不透明、结晶型热塑性聚酯树脂。与PET一起统称为热塑性聚酯，或饱和聚酯。

PBT在中国是最主要的消费领域是电子电器，占55%左右，用在汽车领域大概占10%左右，其他领域约占 35%。随着中国汽车工业和电子/电气产业的高速发展，对PBT的需求量也在快速增长着，PBT系列产品前景在2010年前后仍然是十分看好。回顾2003年全球PBT消费量大约为57万吨/年（基础树脂），需求以北美为主，亚洲由于电子/电器工业需求的驱动，消费量也快速增长。全球PBT分地区的需求量分别为：北美20万吨、西欧16.5万吨、日本9.8万吨、世界其他地区18.8万吨。汽车和电子电气工业消费量占全球PBT总消费量的75%左右，而2004-2006年期间全球需求量已经保持年均8-10%的速度递增。

PBT又可称为热塑性聚酯塑料，为适用于不同加工业者使用，一般多少会加入添加剂，或与其它塑料掺混，随着添加物比例不同，可制造不同规格的产品。由于PBT具有耐热性、耐候性、耐药品性、电气特性佳、吸水性小、光泽良好，广泛应用于电子电器、汽车零件、机械、家用品等，而PBT产品又与PPS、PC、POM、PA等共称为五大泛用工程塑料。PBT结晶速度快，最适宜加工方法为注塑，其他方法还有挤出、吹塑、涂覆和各种方面，如二次加工成型，成型前需预干燥，水分含量要降至0.02%。

PBT是最坚韧的工程热塑材料之一，它是半结晶材料，有非常好的化学稳定性、机械强度、电绝缘特性和热稳定性。这些材料在很广的环境条件下都有很好的稳定性。PBT吸湿特性很弱。非增强型PBT的张力强度为50MPa，玻璃添加剂型的PBT张力强度为170MPa。玻璃添加剂过多将导致材料变脆。PBT的结晶很迅速，这将导致因冷却不均匀而造成弯曲变形。对于有玻璃添加剂类型的材料，流程方向的收缩率可以减小，但与流程垂直方向的收缩率基本上和普通材料没有区别。一般材料收缩率在1.5%~2.8%之间。含30%玻璃添加剂的材料收缩0.3%~1.6%之间。熔点（225℃）和高温变形温度都比PET材料要低。维卡软化温度大约为170℃。玻璃化转换温度（glass trasitio temperature）在22℃到43℃之间。由于PBT的结晶速度很高，因此它的粘性很低，塑件加工的周期时间一般也较低。

Plastic News: In August 2019, Koth was an active participant in the "energy and environment experiment platform for future residential buildings" project sponsored by the China Academy of Building Sciences, and Join Hands with industry partners Zhejiang Deelong Technology Co. , Ltd. and German Green House group, to build custom Baiduo for this project? Solution of glass fiber reinforced polyurethane energy-saving refractory window. The profile is made of alkali-free glass fiber yarn as reinforcing material, polyurethane resin as Matrix Resin, and molded by closed-die injection-pultrusion process, which is energy-saving, fire-resistant and high strength. In response to the project's energy and environmental requirements for the "building of the future, " Koth has teamed up with a partner to develop a new material, koth offers the following three custom window solutions: FOR WINDOWS WITH A K value of less than 1.5, Koth offers both. Among them, "pure thermal insulation 65 open series" using full polyurethane profile, suitable for all kinds of doors and windows project. This profile has the advantages of ultra-low heat conduction, reliable low temperature resistance, excellent mechanical properties and longer service life. At the same time, because the material Coefficient of thermal expansion very close to the concrete, can avoid the window frame and wall due to thermal expansion and contraction difference caused by the gap. The "great The Broken Bridge 65 series" windows and doors are made of costron polyurethane as a thermal insulation bridge, and the surface is covered with aluminum profiles. As the inner heat insulation core, polyurethane composite material can bear the fixed force of the wall and the weight of all glass layers, ensure the wind pressure resistance of the whole window, and make the heat insulation and load bearing integrated. In order to meet the whole window K value less than 0.8 requirements, Koth created a custom "85 open series" full polyurethane profile. The overall use of polyurethane composite profiles, can meet the "passive room" energy-saving requirements. The outer window is made of glass fiber reinforced polyurethane, equipped with double-layer Low-E argon-filled insulating glass. The whole window has a k value as low as 0.77 W/(M2? K) . In addition, the program uses a special sub-frame, energy saving, corrosion resistance and waterproof sealing function is good.
