Polycarbonate and polybutylene terephthalate blends (PC+PBT) combine the properties of PC and PBT, including the high toughness and dimensional stability of PC, and the lubricity and good chemical and heat resistance of crystalline PBT.
Typical Applications of PC+PBT material
Gear cases
Automotive bumpers
Applications which require
– chemical and corrosion resistance
– high heat resistance
– high impact strength over wide temperature ranges
– high dimensional stability
