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性能：PBT树脂为结晶形，熔点230℃左右，相对密度1.35；具有优良的力学性能，有自润滑性和耐磨性，摩擦系数低，耐热、耐候好；但缺口敏感性大；尺寸稳定性好，电性能优良，耐电弧性好；抗化学药品性及其优异，与醇、醚、脂肪烃、酸和盐的水溶液等不起作用，但不耐强酸和强碱。耐，在二中溶胀，在芳烃、中有些溶胀。在改性PBT中，有92%是用玻璃纤维增强的，经过增强改性的PBT性能突出：①耐热性优良，长期使用温度125℃，短期使用温度达210℃；②机械强度高，在长时间高负荷下变形小；③吸水率低，尺寸稳定性好，耐摩擦磨耗性优良。
Types of PBT: 10% glass fiber reinforced, 20% glass fiber reinforced, 30% glass fiber reinforced, flame retardant, mineral filling, glass mineral mixing, high temperature resistance, glass fiber fire resistance, hydrolysis resistance, lubricant addition, heat stabilizer addition, ultraviolet resistance, food grade, thermal conductivity level, high flow.
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.
PBT加工工艺：PBT快的充填速度,一般会使流程加长,适合填充薄壁型材,并形成叫好的表面光洁度.PBT对于厚壁制品,慢速充填有助于减少空隙.PBT当使用窄浇口时,壁厚段的充填速度应减低,以帮助保压.PBT对于小浇口(针尖形浇口)的制件,建议采用程序,开始时可使用较慢的速度,一减少剪切,漩纹和物料的烧焦.PBT 通常我们建议PBT采用中高速的速度,以便提高表面光光泽度和提高接合线强度.量:建议量为机器容量的35%~85%,对于颜色控制严格的混合牌号,PBT建议量尽可能接近机器容量的63%,以减少滞留时间
