1 of 363 products in this brand
MOCOM Compounds ALCOM® PC 740/4.19 WT1302-05LB is a polycarbonate base polymer containing a special filler/additive system with high reflectivity, opacity, and easy flow. It is suitable for applications in the automotive and lighting industry such as light guides, reflectors, and light blocking components. It should be processed using injection molding with a melt temperature of 280-320°C and a mold temperature of 80-110°C. For optimal results, it should be stored in a dry place, away from light, and protected from moisture.
