PC-ABS

A compounded blend of Polycarbonate and ABS. The PC contributes impact and heat distortion resistance, while the ABS contributes processability and chemical stress resistance, and cost reduction below PC.

PC/ABS should be used for appearance housings, and structural parts which need stiffness, gloss, impact and heat resistance which is higher than ABS, but requiring costs below Polycarbonate. Housings requiring UL V0, but not 5VA-that is, portable electronic devices, not permanently fixed electric devices are also good applications for PC/ABS. Others include appearance parts requiring color fastness under interior UV light, automotive interior parts where temperature environment is between 180 F and 230 F - "above the beltline" applications, and where non-shattering ductility is required like instrument panel retainers. Applications such as painted exterior automotive parts requiring low temperature impact greater than 10 ft.-lb. /in. is another place PC/ABS should be used. Any outdoor application should be painted.
