Molecular Formula: Sb2(OCH2CH2))3
Molecular Weight: 423.67
INTRODUCTION:
Antimony ethylene glycol is the most novel catalyst used in polycondensation reaction. The white mini-crystal; can dissolve in the glycol; easy to absorb moisture in the air, and need to be strictly kept sealed.
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.
APPLICATION:
Such as bottle-grade, film-grade and textile chips.
STANDARDS:
