PC-ABS

PC-ABS is a polymer blend that combines polycarbonate's heat resistance and toughness with ABS's easier processability and dimensional stability, striking a middle ground between the two.

About

PC-ABS blends polycarbonate and ABS to offset each material's main weakness: pure PC's high shrinkage makes precise geometries difficult, while standard ABS falls short on heat resistance and impact strength.

The result sits between the two, as the blend offers better heat resistance and impact toughness than ABS alone, with better dimensional stability and easier processing than pure PC. That said, it doesn't match PC's absolute heat resistance.

Because PC-ABS is a blend rather than a single standardized formulation, the ratio of PC to ABS varies between manufacturers, so performance can differ from one supplier's material to another.

PC-ABS suits functional prototypes, electrical enclosures, and automotive or industrial components that need a balance of heat resistance, impact strength, and dimensional accuracy.
