PC/ABS at a glance
PC/ABS is a blend that combines the heat resistance and toughness of PC with the good processability of ABS. Typical uses are housings and vehicle interior parts.
Dry before processing. The processing windows of PC and ABS are close together; keep temperatures tight so the ABS phase is not damaged.
Processing data for PC/ABS
- Melt temperature: 250–270 °C
- Mould temperature: 80–100 °C
- Drying: 3 h at 100 °C
