Ethylene Glycol Antimony |
| Description: |
Ethylene glycol antimony is the most novel catalyst used in polycondensation reaction. Compared with the catalyst of antimony trioxide and antimony acetate, it has the following advantages: 1. the solubility in ethylene glycol solution and good dispersibility. 2. High antimony content, good activity, can improve the plant production capacity. 3. The catalyst won’t bring the impurity, so make the slice improve the intrinsic quality and spinnability. |
