1 of 363 products in this brand
MOCOM Compounds ALCOM® PC 740/4 RD1127-12LD3 is a polycarbonate-based polymer containing a special filler. It is designed for applications such as lamp covers, display elements, and operating elements in automotive and lighting industries. It has a translucent, light-scattering appearance, with good flow characteristics. It should be pre-dried at a temperature of 120°C in a dry air (dessiccant) dryer for 2-4 hours, and 120°C in an air circulating dryer for 4-12 hours, with a maximum moisture content of <0.02%. This polymer has GS93016 approvals, and is processed using injection molding with a melt temperature range of 270-310°C and a mold temperature range of 80-110°C.
