Solve issues with polyester alloys such as discoloration, brittleness, or foaming caused by transesterification. Maintain Heat Distortion Temperature. Avoid loss of molecular weight of your copolymers.

The PET masterbatch is an effective catalyst deactivator for polyester polymerization.

It can significantly improve the thermal stability of polyester alloys such as PC/PBT,PC/PET,PBT/PET, PC/PCTG, PC/PETG alloys.
