Product Description

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.

Advantages	1. Excellent transparency, outstanding resistance to aging. 2. It has good insulating properties and mechanical strength; to acid, alkali, salt has a strong resistance to corrosion; and because easy processing.
Applications	Minsheng supplies (brush bristles, elastic fiber, fluorescent tube, energy-saving bulb shell) Steam Locomotives (Auto Distribution Panels, Handles, Fuse Boxes, Power Windows) Electrical and electronic (optical fiber tube, connector, cooling fan, switch, reel) Industrial (Hot glue gun)
