POLYBUTYLENE TEREPHTHALATE RESIN (NEAT RESIN)

Polybutylene terephthalate (PBT) is a thermoplastic polyester resin produced by having 1.4-butanediol (BDO) and purified terephthalic acid (PTA) going through polycondensation and kneading process. Because it possesses a number of excellent features, it is widely used in the electronics, home appliance, IT, communication, and automotive industries. It is the material that is gaining the most attention among wide range of engineering plastics.
