LEXAN™ Copolymer 943X

About
LEXAN 943X is a UV stabilized medium flow impact modified injection molding (IM) grade. This resin offers UL94 V0 @ 1.5mm flame retardancy based on non-bromine, non-chlorine FR systems, low temperature ductility characteristics and excellent processability with opportunities for shorter IM cycle times compared to standard PC. LEXAN 943X resin is a product available in a wide range of opaque colors and may be an excellent candidate for a wide range of applications.&&
