Plastics Profiler ABS+PC Blends

Featured, Newsletter, Plastics Profiler

ABS+PC are blends of the amorphous engineering thermoplastics, acrylonitrile-butadiene-styrene (ABS) and polycarbonate (PC).  ABS+PC is similar in many ways to its component resins, but combines the mechanical and thermal properties of polycarbonate with the processability and economy of ABS.

Impact Strength: Notched izod values vary considerably based on the composition of the blend and grade of ABS used. A typical value for general purpose ABS+PC is around 12 ft-lb/in or midway between ABS and PC. A key strength of ABS+PC is cold temperature impact resistance at low temperatures.

Thermal: ABS+PC have good thermal stability with heat deflection temperatures in the range of 205-240 F at 264 psi load, again midway between ABS and PC.

Chemical Resistance: ABS+PC blends carry some of the weaker characteristics of their base resins so they are not well suited to long term hot water or steam applications nor contact with ketones and low molecular weight solvents. However, ABS+PC can be more chemically resistant than the separate component resins.
