Description

Antimony Glycolate（ATG）serves as a highly effective catalyst for polyester polycondensation, with its primary application lying in polyester industrial manufacturing. It represents the third - generation antimony - based catalyst, succeeding antimony trioxide and antimony acetate. Antimony glycol exhibits remarkable features such as high catalytic activity, a rapid catalytic reaction rate. It ensures the production of polyester of superior quality, endowing it with excellent spinnability.

This catalyst finds extensive use in the production processes of polyester fiber and non - fiber - related chips. Specifically, fiber - grade chips and bottle - grade chips, produced with the help of antimony glycol, can function as raw materials for a wide range of clothing fabrics and plastic bottles.

Antimony glycol stands out as the most innovative catalyst employed in polyester polycondensation reactions. When contrasted with antimony trioxide and antimony acetate, it offers multiple advantages:

It demonstrates excellent solubility in glycol solutions, enabling remarkable dispersion capabilities.

With a high antimony content, it exhibits robust catalytic activity. This not only enhances the catalytic efficiency but also boosts the production capacity of relevant manufacturing equipment.

Since this catalyst does not introduce any new impurities, it effectively elevates the internal quality of polyester chips. As a result, it significantly improves the spinnability during post - processing procedures.
