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.
●Characteristics
1,Excellent combination of clarity and weatherability
2,Excellent combination of clarity and chemical resistance
3,Excellent flo
Sabic Xylex resin X7300 is a PC+POLYESTER unreinforced alloy. High flow, chemically resistant with excellent optical quality. UV-stabilized.
