S-Plastics Lexan ML7667 resin isspecialty polycarbonate (PC) resin is a 9% GF reinforced, UV stabilized, flame retarded injection molding grade. This
medium flow specialty PC resin combines UL94 V0 @ 1.5mm, 5VB @ 3.0mm flame retardancy based on non-chlorine, non-bromine FR
agents with excellent processability, improved release performance and good impact performance. This product is available in limited
opaque colors only and may be an excellent candidate for a broad range of applications, i.e. electrical and electronic enclosure
applications.
