1 of 363 products in this brand
MOCOM Compounds ALCOM® PC 740/171 GY1127-04LD is a pre-dried polycarbonate composite that provides a translucent, light scattering, and high light diffusion due to its special filler/additive system. It is GMW15702 approved and suitable for automotive and lighting applications such as lamp covers, display elements, and operating elements. Injection molding should be done with a melt temperature of 270-310°C and a mold temperature of 80-110°C. Additionally, it should be stored in a dry, light-protected area.
