PC-ABS - Polycarbonate/Acrylonitrile Butadiene Styrene

PC-ABS (Polycarbonate/Acrylonitrile Butadiene Styrene) is a blend of PC and ABS providing unique combination of the high processability of ABS with the excellent mechanical properties, impact and heat resistance of PC.

The PC-ABS property balance is controlled by the ratio of PC and ABS in the blend, the polycarbonate molecular weight and the additive package. The ratio of polycarbonate and acrylonitrile-butadiene-styrene affects mainly the heat resistance of the final product. PC-ABS blends exhibit a synergic effect resulting in excellent impact resistance at low temperatures that is better than impact resistance of ABS or PC.

Major PC-ABS brands are Pulse®, Bayblend® and Cycoloy®.

Main PC-ABS properties are:

  • High impact strength even at low temperatures;
  • Heat resistance;
  • High stiffness;
  • Easy processing;
  • Low overall shrinkage and high dimensional accuracy;
  • Colourable & printable.

PC-ABS resins fit into applications that require a high heat distortion temperature (95-125°C) and good toughness. They have excellent low temperature toughness, making them ideally suited for products that will see a broad range of temperature.

Typical PC-ABS applications are:

Automotive:
  • Middle console;
  • Glove box;
  • Lower instrument panel;
  • Pillars:
  • Knee bolster;
  • Overhead console;
  • Blow moulded seatbacks;
  • Structural components.
Electronics:
  • TV frames;
  • Laptop monitor enclosures;
  • Portable hand-held devices;
  • LCD panels;
  • Keypads;
  • Adapters and chargers;
  • Mobile phone bodies.
