Heat-resistant modified unsaturated polyester molding compound PT-310 for insulating parts
Characteristics : Heat-resistant modified unsaturated polyester molding compounds possess high resistance against electrical arc and tracking, superior mechanical strength, excellent long-term dimensional stability even at elevated temperature and good flame resistance to UL94 V-0. It has over 12 months of storage time at room temperature. PT-310 molding compounds have obtained UL certificate No. E208587.
Advantage: High proof tracking index, high resistance against electric arc, superior dielectric strength, high charpy impact strength(notched), high heat resistance and flame resistance, low water absorption, and excellent long-term dimensional stability.
Applications: Mainly used to the insulating parts for temperature controllers for household appliances, main switches, magnet coil frames, connecting terminals, low-voltage devices and flameproof devices, etc.
