PC/ABS Alloy : Non Reinforced Grade Classification: General purpose>Injection grade Characteristic: Injection grade, high impact Resistance Application: GAC 244 is an unreinforced PC/ABS alloy which offers good impact strength and high heat resistance. Especially, metal plating is very easy with GAC 244. So GAC 244 could be used outdoor housing which need metal plating such as, automotive door handle, lamp housing, etc
