巴斯夫股份公司（BASF SE），缩写BASF是由以前的全名「Badische Anilin-und-Soda-Fabrik」（巴登苏打厂）而来，是一家德国的化工企业，也是世界的化工厂。
BASF se (BASF SE), abbreviated BASF from the former full name "Badische anilin und soda factory", is a German chemical enterprise and one of the largest chemical plants in the world.
The development of PBT: PBT was first developed by German scientist P. Schlick in 1942. Then Celanese company (now Ticona) in the United States carried out industrial development and listed under the trade name of celanex. In 1970, it was put on the market with 30% glass fiber reinforced plastic, the trade name was x-917, and later changed to celanex. In 1971, Eastman company launched a glass fiber reinforced chain and non reinforced products, trade name tenite (ptmt); in the same year, GE company also developed similar products, with three varieties of non reinforced, reinforced and self extinguishing. Subsequently, world famous manufacturers such as BASF, Bayer of Germany, GE and Ticona of the United States, Toray of Japan, Mitsubishi Chemical of Japan, new optical fiber of Taiwan, Changchun artificial resin, South Asia plastics and other companies successively put into production. There are more than 30 global manufacturers.
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
