安徽快3万能:The best Flame Retardant of Polycarbonate (PC)—— Potassium Perfluorobutyl sulfonate

安徽快3讨论 www.tkkxz.com

Polycarbonate (PC) is a kind of thermoplastic engineering plastic with excellent comprehensive performance. It has high impact strength, high light transmittance, good dimensional stability, easy coloring, good aging resistance, and excellent electrical insulation. PC is widely used in electronics, electrical appliances, aerospace, machinery, automotive textiles, light industry and construction industry.


Perfluoro Surfactant factory.jpgPC has flame retardant, but it is still difficult to meet the requirements of flame retardancy   in some application fields, such as TV, computer, printer casings and components, transformer coils, automobile parts, building materials, etc. In addition, the hot melt dripping during PC burning   can easily cause nearby materials to catch fire.. Therefore,   it is necessary to modify the flame retardant of the PC.


Studies have shown that the addition of a very small amount of 0.1% potassium perfluorobutane sulfonate can significantly improve the flame retardant grade and oxygen index of PC. The flame retardant properties of the material reach UL94V-0 and can prevent droplets from dripping.


The flame retardant mechanism is: the flame retardant emits sulfur trioxide under the action of heat and flame to cause the PC to expand and rapidly decompose to form a carbon layer, thereby preventing heat and oxygen from diffusing into the material.
