ST-T78MB

Specialty Additive

ST-T78MB

Transesterification Inhibitor. Solve issues with polyester alloys such as discoloration, brittleness, or foaming caused by transesterification. Maintain Heat Distortion Temperature and avoid loss of molecular weight in copolymers.

Suggested Resins

PC/PBT, PC/PET, PBT/PET, PC/PCTG, PC/PETG alloys.

Application Examples

Any polyester copolymer where discoloration, brittleness, poor thermal performance or foaming is an issue. This PET masterbatch is an effective catalyst deactivator for polyester polymerization. It significantly improves the thermal stability of polyester alloys such as PC/PBT, PC/PET, PBT/PET, PC/PCTG, and PC/PETG alloys.
