Commonly used materials for laptop plastic casings include PC/ABS, PC+GF, PPS, etc., among which PC/ABS is the mainstream. PC/ABS is an engineering plastic alloy obtained by blending and modifying PC and ABS. It not only has the excellent heat and weather resistance, dimensional stability and impact resistance of PC resin, but also has the excellent processing fluidity of ABS resin. It can be used to manufacture thin-walled and complex-shaped products with excellent performance, such as consumer electronics casings such as mobile phones/laptops.
