  • Product Details
  • Parameter

1. The solubility of Catalyst S-24 in ethylene glycol (MEG) is more than 3% at 60°C.

2. The antimony content per kilogram of Catalyst S-24 is higher than that of all other antimony catalysts which can be dissolved in ethylene glycol.

3, Catalyst S-24 is low trace metal contents, high purity, used in PET production .

4, Catalyst S-24 can be well dissolved in ethylene glycol, its solution in vacuum can remain stable for a long time.

5, Catalyst S-24 has good solution stability due to its single structure.

6, Catalyst S-24 can quickly participate in the polymerization chain growth of monomers, so as to shorten the catalytic time, and make the reaction can be carried out at a lower temperature.

7, Minimize the loss of antimony in ethylene glycol recovery.

Packaging: Catalyst S-24 is packed in high density polyethylene (HDPE) drums weighing 25.0 kg net. Each 18 barrels are stacked on a card board and packed in a carton.
