It is a very versatile engineering plastic and is widely used in the automotive industry, electronic and electrical industry, light industrial home appliances, textiles and Construction and other industries. Blending PC and ABS can combine the excellent properties of both. On the one hand, PC/ABS alloy has better heat resistance, impact strength and tensile strength than ABS.
