Quality index: This product is ethylene glycol antimony crystal, and its quality index as a polyester catalyst is shown in the following table:

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.

Scope of application: Mainly used as a polyester catalyst
Packaging and storage: Packed in polyethylene plastic barrels, lined with double-layer polyethylene plastic bags, with a net weight of 12.5kg per barrel, sealed and stored in a dry place away from light, moisture-proof and sun-proof.
Note: This product should not be in contact with the skin.
