S-Plastics Lexan EXRL0300 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. Lexan EXRL0300 is a developmental
product that is an excellent candidate for a wide variety of applications requiring resins modified with anti-microbial additives.
