Sabic Xylex resin is a copolymer of transparent polycarbonate (PC) and amorphous polyester. Compared with PC, adding polyester to xylex resin provides enhanced chemical resistance against certain fluids and improves the stress cracking resistance of the resin.
Sabic Xylex resin X8300 is a transparent, UV stabilized polycarbonate (PC) and polyester alloy. Exhibits good weather resistance, enhanced chemical resistance, lower processing temperatures. Is suitable for processing by injection molding.
