Product Description
PBT is a thermoplastic, and in order to be used by different processors, additives are generally added or blended with other plastics, and with different ratios of additives, different specifications of products can be manufactured. Because of its heat resistance, weather resistance, chemical resistance, good electrical characteristics, low water absorption, and good gloss, PBT is widely used in electronics, automotive parts, machinery, household products, etc. PBT products are also known as the five major general engineering plastics together with PC, POM, PA, etc.Communication field: Integrated modules, wiring boards, electric tools, etc. for programmable telephones.
