PC/ABS Polymer Supplier UK

Polycarbonate/Acrylonitrile-Butadiene-Styrene Blend

PC/ABS is one of the most widely used engineering polymers. It is produced from a blend of PC and ABS.

It provides a great combination of the very good processing characteristics of ABS along with the excellent mechanical properties, impact and also the heat resistance of PC.

Within the automotive sector, PC/ABS is a material in particularly high demand.

The growing move towards customer personalisation within the vehicle has led to significant change in the design of automotive interiors as consumers look for a more individual experience.

Car interiors now offer improved functionality and a much more elegant and luxurious appearance in order to satisfy this desire.

PC/ABS is widely used in both interior and exterior applications due to its excellent balance of mechanical properties and ease of processing but the downside is that these materials typically produce less attractive, high-gloss surfaces.

To eliminate this issue, parts often require texturing or painting to deliver the desired low gloss appearance associated with the premium car brands.



All blends are produced using a compounding step to blend the polymers. This compounding technology is most important for creating the optimal conditions for homogenisation and interaction between the two phases.

Using a combination of the right additives, for example: flame retardant additives, stabilisation packages, and impact modifiers for improved reinforcement, blends are produced with an optimum set of balanced properties.

The balance between the PC and the ABS affects mainly the heat resistance of the polymer.
