PC+ABS is a thermoplastic engineering plastic commonly used in injection molding. It is a blend of Polycarbonate

 (PC for short) and Acrylonitrile Butadiene Styrene (ABS for short). The material combines the high strength and 

thermal stability of PC with the processing convenience and toughness of ABS.

Here are some advantages and disadvantages of PC+ABS:

Advantages:

Overall excellent performance: PC+ABS compromises the high strength, good heat resistance and high impact 

resistance of PC, as well as the good processability, excellent toughness and cost efficiency of ABS.

Good thermal stability: PC+ABS blends have a high thermal deformation temperature and can be applied at higher temperatures.

Excellent impact resistance: PC+ABS can maintain good impact strength, especially at low temperatures.

Good plasticity: can be processed by injection molding, extrusion molding and other ways, strong adaptability, can 

produce a variety of complex shapes of products.

Excellent surface finish: The surface of products made of PC+ABS is generally smooth, suitable for painting, printing and coating.

Stable electrical performance: PC+ABS has good electrical insulation and is suitable for the manufacture of electronic 

and electrical enclosures or components.

Cons:

Compared with pure PC, chemical resistance is slightly reduced: although the PC component provides better chemical 

resistance, the chemical resistance of PC+ABS is slightly inadequate compared with pure polycarbonate.

Water absorption: PC+ABS has certain water absorption, which may affect the processing process and mechanical properties.

Thermal aging: Long-term exposure to high temperatures, the performance of PC+ABS may decline, pay attention to 

the limit of the temperature range when using.

High cost: Compared with pure ABS, the cost of PC+ABS is usually higher due to the addition of PC.

Processing requirements: High requirements for processing equipment and process conditions, it is necessary to maintain 

the material properties at the same time, control the molding process conditions, especially the temperature, pressure, 

cycle time during injection molding.

Overall, PC+ABS is a balanced performance of engineering plastics, often used in the manufacture of automotive parts, 

electronic and electrical casings, medical equipment, protective equipment and other fields. In the specific selection and

design, it is necessary to consider the application environment and performance requirements of the product, choose 

whether to use PC+ABS and how to design to maximize its performance.
