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 includingelectrical properties), high dielectric ability, good electrical capacity, size stability, good formability, excellent anti-creepability under high impact, and good chemical properties as well. It is easy to process into glass-fiber reinforced and flame-retardant products.
