Polybutylene terephthalate (PBT) is a polyester made by polycondensation of terephthalic acid and 1,4-butanediol. It is an important thermoplastic polyester and one of the five major engineering plastics. Polybutylene terephthalate is a milky white, translucent to opaque, semi-crystalline thermoplastic polyester with high heat resistance. It is not resistant to strong acids and alkalis, but is resistant to organic solvents, flammable, and decomposes at high temperatures.e.
Advantages
Excellent mechanical properties, especially high rigidity and hardness
Good heat resistance, heat deformation temperature can reach above 180ºC
Good surface gloss performance, especially suitable for spray-free electronic and electrical products
Fast crystallization speed, good fluidity, excellent formability
Good thermal stability, especially low thermal expansion rate and dimensional shrinkage rate
Good resistance to chemicals, solvents and weathering
High dielectric strength and good electrical properties
Low hygroscopicity, minimal effect on electrical and dimensional stability
