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.
PBT非增强树脂密度1.3-1.45kg/cm3,硬度85-90M,吸水率0.03-0.06%,流动方向成型收缩率0.8-2%,垂直方向成型收缩率1.2-2.2%,弯曲强度75-95Mpa,简支梁缺口冲击(ISO179)2-6,热变形温度(1.8Mpa)50-75,热变形温度(0.45Mpa)130-163,熔点225℃,
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。
PBT被广泛用于电子电器领域应用占PBT的总生产量的百分之五十:电脑/电器接插件、接触器、线圈骨架、连接器、继电器、熔断器、调节器、温控开关、温控保护器、装饰灯座、开关插座、电磁炉底盘、电暖器出风口、散热扇翼、变压器线圈骨架、高电压大电流的高压断路开关骨架、电脑风扇、节能灯灯头、电器开关、电子镇流器外壳、电吹风、电烤箱、电饭煲、微波炉、水泵配件及电动工具配件等;PBT汽车领域的应用占PBT的总生产量的百分之三十:主要用于高压无触点点火器的分电器盖、转子、点火线圈盖、接线端子、传感器盒、前后灯座、集成电路盒、微电机后盖、冷气风扇等,PBT通讯领域应用占PBT的总生产量的百分之二十,主要用于程控电话的集成模块、接线板、电容器外壳、天线护套等.
