Characteristics of PC / ABS and its application in automobile industry

Time:2021-07-14

Polycarbonate (PC) is a kind of engineering plastics with excellent comprehensive properties, and its output is second only to polyamide (PA). It has excellent properties such as impact resistance, dimensional stability, heat resistance, transparency and so on. It is widely used in electronic and electrical appliances and automobile manufacturing industry. Today, Ruiyuan engineering plastics manufacturer will share with you the characteristics of PC / ABS and its application in the automotive industry.

Compared with ABS, C / ABS alloy can improve heat resistance, impact resistance, surface depression, warpage and other defects. Compared with PC, it can improve the fluidity, processing performance, reduce the sensitivity of products to stress, and reduce the production cost.

Taking automotive applications as an example, ABS / PC alloy is more suitable for automotive interior parts, which has excellent heat resistance, mechanical properties and good processing fluidity. The Vicat softening temperature of ABS / PC alloy automobile instrument panel can reach 110-135 ℃, which can fully meet the heating requirements of tropical countries, hot summer at noon when cars Park outdoors; In addition, the instrument panel can be directly sprayed with soft topcoat or coated with PVC film without surface pretreatment due to its good finishing and adhesion to the covering film. ABS / PC alloy is also used to manufacture automobile parts such as parts around instrument panel, antifreeze panel, door handle, shade board, bracket, steering column sheath, decorative panel, air conditioning system accessories, etc.
