BASF is headquartered in Ludwigshafen, with more than 350 branches and companies in 39 countries. Among them, there are more than 60 domestic manufacturers in Germany, respectively located in Ludwigshafen, Minster, Hamburg, Stuttgart, Mannheim, welzburg, Cologne and other cities. BASF Group headquarters and BASF joint stock company in Ludwigshafen are like a "small city", covering an area of 7 square kilometers.
PBT的种类：10%玻纤增强、20%玻纤增强、30%玻纤增强、阻燃、矿物填充、玻矿混合、耐高温、玻纤防火、耐水解、润滑剂添加、热稳定剂添加、耐紫外线、食品级、导热级、高流动。
Overview of PBT development: in the early 1970s, PBT was successfully researched by Celanese company of the United States, and was listed under the trade name of celanex. Subsequently, world famous manufacturers such as BASF, Bayer, Ge, Ticona of the United States, Toray and Mitsubishi Chemical of Japan, new optical fiber of Taiwan, Changchun artificial resin and South Asia plastic materials were successively put into production. There were more than 30 global manufacturers. PBT can also be called thermoplastic polyester plastics. In order to be suitable for different processing industries, additives are usually added or mixed with other plastics. With the different proportion of additives, different specifications of products can be manufactured. At present, there are more than 100 specifications in the island, so PBT is a product with less quantity and more specifications.
It is characterized by good acid resistance, good salt resistance, high temperature resistance to water and salt, high temperature resistance to water and salt, good resistance to water and salt, good resistance to water and salt, good resistance to water and salt Use, but not resistant to strong acid and alkali. It is resistant to carbon tetrachloride, and swells in dichloroethane, some in aromatic hydrocarbon and acetic acid. Among the modified PBT, 92% is reinforced by glass fiber, and the properties of the modified PBT are outstanding: ① excellent heat resistance, long-term service temperature of 125 ℃, short-term service temperature of 210 ℃; ② high mechanical strength, small deformation under long-term high load; ③ low water absorption, good dimensional stability and excellent friction and wear resistance
PBT加工之前必须要行干燥处理、要将水分含量控制在0.03％以下。
PBT采用热风循环干燥时，PBT当温度为110℃、115℃或145℃时，所对应的时间不**过六小时。料层厚度低于32mm。
PBT温度:PBT的分解温度为285℃，所以实际生产中控制在235-265℃：
PBT压力压力为52～102MPa。
PBT速率 PBT冷却速度快，因此要采用较快的速率。
螺杆转速和背压成型PBT的螺杆转速不宜**过80r/min，在25～62r/min之间。
背压为压力的12％～17％。PBT模具温度在65～82℃，各部位的温度差不**过12℃。PBT成型时间一般情况下为18～62s。
