PC ABS Alloy Series

PC/ABS alloy combines the excellent performances of both PC and ABS. On the one hand, it can improve the heat resistance and tensile strength of ABS, and on the other hand, it can reduce the melt viscosity of PC, improve the processing performance, decrease the sensitivity of products to stress and reduce cost. PC/ABS alloy is the most mature product of Lijia Company which has developed several series such as high impact resistance, high flow, flame retardant and mineral reinforced series applied to auto grille, handles, electrical and electronic shell and switch panel in large quantities. In addition, the company has also developed PMMA/ABS and PA/ABS alloys, etc. widely used in home appliances shell and auto inner decoration parts.
