What Is PC/ABS?

PC/ABS blends polycarbonate with acrylonitrile butadiene styrene. The result is a material family that can combine PC toughness and heat resistance with the easier processing and surface appearance associated with ABS.

Properties

Higher heat resistance than standard ABS

Improved impact strength and toughness balance

Good dimensional stability for assembled housings

Better stress resistance for snap fits and loaded parts

Can be formulated for flame retardance and controlled appearance

PC ABS key properties for impact strength heat resistance and surface quality

Advantages

Performance Upgrade From ABS

PC/ABS keeps much of the processability and surface quality of ABS while extending heat and impact capability.

Useful For Functional Housings

The blend is well suited to parts that must survive assembly load, screw bosses, clips, vibration, and moderate heat exposure.

Flexible Compound Platform

Grades can be adjusted for flame retardance, flow, stiffness, color, appearance, and application-specific testing.

PC ABS injection molding material processing for industrial plastic parts

Processing Support

PC/ABS processing should consider drying, melt stability, gate design, surface appearance, and dimensional control during injection molding.

PC ABS compounding production line for customized engineering plastics

Production Capability

Custom PC/ABS compounds can be adjusted for impact, flame retardance, flow, color, appearance, and application-specific production requirements.

Automotive Applications

Interior Trim and Covers

PC/ABS can support interior parts where impact, appearance, heat aging, and dimensional stability are all relevant.

Automotive Electrical Parts

Flame retardant PC/ABS may be evaluated for selected electrical housings, modules, and safety-related covers.

PC ABS material applications for automotive electronics and appliance components

Electrical Applications

Electronics Housings

PC/ABS is often considered for device housings that need toughness, better heat performance, and stable molded quality.

Flame Retardant Materials

FR PC/ABS compounds can support electrical and electronics applications when flame rating and wall thickness requirements are defined.

Quality Testing

PC/ABS material selection should be supported by grade review, TDS comparison, molding trial feedback, and quality testing for the target application.
