PC/PBT is an amorphous blend of polycarbonate (PC) and semi-crystalline polybutylene terephthalate (PBT).
By mixing two polymers, it is possible to achieve a blend that makes use of the best possible combinations of the properties of both materials. The semi-crystalline structure of PBT contributes rigidity and resistance to chemicals and UV light, and PC contributes with excellent impact resistance and dimensional stability.
This blend can be used in many different applications, and is very commonly used in e.g. the automotive industry.
Primary properties:
- Very good impact resistance (even at low temperatures, down to -20°C)
- Good rigidity
- Good UV resistance
- Very good heat resistance
- Good chemical resistance
