ALCOM® PC 740/4 GY1227-08LD

Chemical Family: Polycarbonate (PC)

MOCOM Compounds ALCOM® PC 740/4 GY1227-08LD is a polycarbonate base polymer with a special filler/additive system for light scattering and high light diffusion, as well as easy flow. It is approved by GS93016 and is typically used for lamp covers, display elements, and operating elements in the automotive and lighting markets. The melt temperature for injection molding is 270-310°C and the mold temperature is 80-110°C. It should be protected from light and stored in a cool, dry place away from sources of heat.
