Because PBT has heat resistance, weather resistance, chemical resistance, good electrical properties, low water absorption and good gloss, it is widely used in electronic appliances, auto parts, machinery, household goods, etc. In China, PBT resin application distribution ratio In order: electronic and electrical applications nearly 60%, construction machinery and automotive sector about 24%, fiber sheath coating accounted for 8%, PBT fiber accounted for about 3%, the other 5%. Especially in today's automobile market driven by the trend of plastic-generation steel and high-performance electronic components, the growth rate of PBT demand has been maintained at an excellent pace. Historical data shows that the growth rate of PBT materials has remained at 13% in recent years. Above, as far as the current situation is concerned, the large consumer market is still occupied by the electronics industry. The specific applications include the output transformer skeleton, the brush holder, the igniter and electrical switch of the electrical industry, and the high voltage package. Among them, PC/PBT materials can be found in high-class cars. Because of low temperature impact strength, easy coating and good chemical resistance, the car floor and the guard plate are widely used in automobile bumpers.
In recent years, the global demand for PBT resin has increased in Asia, with a demand of about 1 million tons in 2009. Mainly concentrated in the field of PBT modified engineering plastics, the downstream market includes automotive, electronic appliances, business machines, lighting and other industries.
