Production 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.
The application fields are similar to thermal conductive PA, and it is mainly used in large-sized lighting fixtures with high toughness requirements
