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.

PC/ABS blend structure.

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
