ALCOM® PBT 700/2 WT31-956LB

Chemical Family: Polyesters

MOCOM Compounds ALCOM® PBT 700/2 WT31-956LB is a Polybutylene Terephthalate base polymer with a special filler/additive system that provides high stiffness and a highly reflective, opaque finish. It is used in the automotive and various other market segments for applications such as lighting, light blocking components, light guides, and reflectors. It can be processed for injection molding with a melt temperature of 250-270°C and a mold temperature of 80-120°C. For optimal performance, it should be stored in a dry and light-protected environment.
