PC-ABS filament
An alloy combining PC's strength with ABS's ease of processing.
What is PC-ABS?
PC-ABS is a plastic alloy widely used in electronic housings and automotive interior trim. It is easier to print than PC and tougher and more heat resistant than ABS.
- Heat resistant
- High strength

Frequently asked questions about PC-ABS
What is PC-ABS?
PC-ABS is a plastic alloy widely used in electronic housings and automotive interior trim. It is easier to print than PC and tougher and more heat resistant than ABS.
Is PC-ABS heat resistant?
The heat deflection temperature (0.45 MPa) of PC-ABS is about 105 °C. This is high; it can be used near engine bays, in hot air and steam.
Can PC-ABS be used outdoors?
It can degrade under prolonged sunlight and UV light. For outdoor use, ASA or another UV-resistant material should be preferred.
Which parts are made with PC-ABS?
PC-ABS is typically used in applications such as electronic housings, automotive interior trim, power tool housings.
Which material can be used instead of PC-ABS?
Depending on the application, PC, ABS, ASA can be alternatives. You can see the differences in the comparison tables on the material pages.
