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