Polybutylene terephthalate

Polybutylene terephthalate (Polybutylene terephthalate), also known as polytetramethylterephthalate. PBT for short. It is a condensed polymer of terephthalic acid and 1, 4-butanediol. Together with PET, PBT is called thermoplastic polyester.

Characteristic application

Characteristics and application of polybutylene terephthalate (PBT)

peculiarity

a, mechanical properties: high strength, fatigue resistance, dimensional stability, creep is also small (there is little change under high temperature conditions);

b, heat resistance aging: enhanced UL temperature index of 120~140℃ (outdoor long-term aging is also very good);

c, solvent resistance: no stress cracking;

d, water stability: PBT is not easy to decompose in water;

e, electrical performance:
