ALCOM® HTC 300/1 GY1055-10LD

Chemical Family: Polyesters

MOCOM Compounds ALCOM® HTC 300/1 GY1055-10LD is a high-temperature copolyester base polymer with a special filler/additive system that has translucent, light-scattering, and high light diffusion properties. It is typically used for automotive and lighting applications such as lamp covers, display elements, and operating elements. To ensure the best performance, it should be stored in a dry, light-protected environment. When processing injection molding, a melt temperature of 260-280°C and a mold temperature of 50-70°C should be used.
