| Usages: |
| Antimony glycolate is the most novel catalyst used in the polycondensation of polyester. It has the following advantages compared with the catalysts of antimony trioxide and lanthanum acetate. |
| 1. It has high solubility in ethylene glycol and good dispersibility. |
| 2. High antimony content, good activity, can increase the production capacity of the device. |
| 3. The catalyst itself does not bring in new impurities, which can improve the intrinsic quality of the chips and improve the spinnability of the post-processing. |
