PBT application field
PBT resin is mostly processed into the use of mixing, after a variety of additives modified, and other resins blend can obtain good heat resistance, flame retardant, electrical insulation and other comprehensive properties and good processing performance. Widely used in electrical appliances, automobiles, aircraft manufacturing, communications, household appliances, transportation and other industries. For example, PBT modified by glass fiber can be used to manufacture electronic components requiring long-term stability at higher temperatures. PBT breakdown voltage is high, suitable for the production of high voltage resistance parts, because of its molten state of good liquidity, suitable for injection processing of complex structure of electrical parts, such as integrated circuit socket, printed circuit board, computer keyboard, electrical switch, fuse, temperature control switch, protector, etc.. Car bumper, carburetor, spark plug, fuel supply system parts, igniter, etc. In the field of communication PBT is widely used in program-controlled telephone integration module, terminal board, power tools and so on.
Introduction of PBT,
Polybutylene terephthalate (PBT) is a polyester made from the condensation of terephthalic acid and 1, 4-butanediol. It is an important thermoplastic polyester and one of the five engineering plastics.
Polybutylene terephthalate is a milky translucent to opaque, semi-crystalline thermoplastic polyester with high heat resistance. Resistant to strong acid, alkali, organic solvent, flammable, high temperature decomposition.
Polybutylene terephthalate is widely used in automobile, mechanical equipment, precision instrument parts, electronic appliances, textiles and other fields.
PBT is non-toxic and has no stimulating effect on the skin. There are adverse environmental impacts in the production process, which need to be addressed.
PBT resin is packed with plastic lining or plastic woven bag, stored in dry, ventilated, rain, sun place storage, away from high temperature, open fire, avoid mixing and transportation with strong acid, strong alkali, strong oxidant.
