PC + ABS blend.
Best of both.
Premium plastic.
PC-ABS — polycarbonate + acrylonitrile butadiene styrene blend. Combines PC strength + ABS processability. Standard for automotive interior, mobile devices, premium consumer products.
Key principles.
Polymer blend
PC matrix + ABS dispersed phase. Synergistic properties.
UTS 60 MPa
Higher strength than ABS, easier to mold than pure PC.
HDT 110°C
Significantly better than ABS (90°C). Approaches PC.
Excellent
Notched Izod 50-70 J/m. Top-tier impact resistance.
Easier than PC
Lower melt viscosity than PC. Wider processing window.
Premium
~$5-7/kg. Higher than ABS, lower than premium PC grades.
FAQ
When PC-ABS over pure PC?
