PBT

Polybutylene Terephthalate

PBT plate bar is a profile processed with PBT material, can be used as engineering structural parts material, is one of the five engineering plastics, at higher temperatures and lower temperatures, have excellent impact performance, wear lower than POM material, long-term use temperature in -40-110°C. The modified material has better mechanical properties and better temperature resistance.
