Product features:

 

Ethylene glycol antimony has the following features compared with antimony trioxide and antimony acetate:

 

1. The molecular structure of the catalyst makes it easier to have electron transfer with polyester molecular which shows a higher catalytic activity.

 

2. It won't bring any impurities to polycondensation, is cleaner than antimony trioxide and antimony acetate.

 

3. It contains the highest antimony content among all soluble antimony catalysts.

 

4. Polyester products have better colors and lustre and thermal stability.

 

5. It has wide applicability, and can be applied to ester exchange and direct esterification process, existing allocate facilities do not need to be modified.

 

6. It can improve the application environment of catalyst, and reduce the production cost of polyester.


Scope of Application: mainly used as polyester catalyst
