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.
