PBT polybutylece terephthalate resin
 

Product Description

Product Description

PBT(polybutylece terephthalate) it is one of the advanced engineering plastics with high rigidity, high toughness, good fatigue resistance, weather resistance, low water absorption rate (all the properties maintain under moisture atmosphere including electrical properties), high dielectric ability, good electrical capacity, size stability, good formability, excellent anti-creep ability under high impact, and good chemical properties as well. It is easy to process into glass-fiber reinforced and flame-retardant products. PBT/PET can be ultrasonic welded and easily post-processed.

Feature:

1.High toughness, high modulus, low creep
2.Good dielectric strength
3.Good dimensional stability
4.Low water absorption rate, good hydrolysis resistance
5.Good heat resistance, low coefficient of thermal expansion
6.High impact strength
7.Resistance to Thermal aging
8.Easy to process
