PC+PBT materials

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

• gear cases

• automotive bumpers

• applications which require

  • chemical and corrosion resistance
  • high heat resistance
  • high impact strength over wide temperature ranges
  • high dimensional stability
