S-Plastics Lexan EXL1414B resin is polycarbonate (PC) siloxane copolymer resin is a BLACK ONLY injection molding (IM) grade modified with anti-microbial additives. This resin offers extreme low temperature (-40 C) ductility in combination with medium flow characteristics and excellent processability with opportunities for shorter IM cycle times compared to standard PC resin. Lexan EXL1414B is an excellent candidate for a wide variety of applications requiring resins modified with anti-microbial additives.
