Ethylene Glycol Antimony

Category:

Product features: Compared with antimony trioxide and antimony acetate, ethylene glycol antimony has the following characteristics: 1. The molecular structure of the catalyst makes it easier to transfer electrons with polyester molecules, thus showing higher catalytic activity. 2. It will not bring any impurities to the polycondensation reaction and is cleaner than antimony trioxide and antimony acetate. 3. The antimony content is the highest among all soluble antimony catalysts. 4. Polyester products have better color and thermal stability. 5. Wide applicability, applicable to transesterification and direct esterification processes, and the existing preparation facilities do not need to be changed. 6. It can improve the catalyst application environment and reduce the production cost of polyester.
