PC/ABS Alloy Balanced Impact – Heat Resistant Plastic for Injection Molding Housings

PC/ABS Alloy | Balanced Impact & Heat Resistant Plastic for Housings

PC/ABS Alloy is a balanced engineering plastic combining the toughness of ABS with the heat resistance of polycarbonate. Ideal for electronic housings, automotive interior parts, and consumer product enclosures requiring impact resistance, dimensional stability, and excellent processability.

Quick Summary: PC/ABS Alloy is a versatile engineering plastic that combines the impact resistance and processability of ABS with the heat resistance and mechanical strength of polycarbonate. Designed for injection molding applications requiring balanced performance, PC/ABS is widely used in electronic housings, automotive interior components, and consumer product enclosures where toughness, dimensional stability, and surface quality are critical.

 

PC/ABS Alloy (Polycarbonate / ABS Blend)

Balanced Engineering Plastic for Structural & Appearance Housings

PC/ABS Alloy is engineered to bridge the performance gap between polycarbonate and ABS. By blending these two polymers at a controlled ratio, PC/ABS delivers excellent impact strength, improved heat resistance, and good surface finish, while remaining easier to process than pure PC.

Compared with standard ABS, PC/ABS offers higher thermal performance and better toughness. Compared with PC, it provides improved flowability and cost efficiency.
