Ethylene glycol antimony

Product Details:

Sb2(OCH2CH2O)3

Purity:           53-56

Appearance:      White microcrystalline powder

Description:

Main application: As the catalyst for poly-condensation of polyester, it is a very active polycondensation catalyst and can be added at either the direct esterification or the polycondensation stage of the process .It is optimized for use in conjunction with the titanium based polyester catalyst technology. The absence of the acetate anion can be an advantage to some polyester manufacturers.
Predictable performance, the consistent high purity to ensure that process variability is minimized .The absence of higher oxidation states and inserts improves polymer quality and process operability .Stability and Solubility: it dissolves readily in ethylene glycol to form a stable solution with high activity.

Physical and chemical indicators and its characters: It can dissolve in the glycol, and can speed up the condensation reaction rate; its catalytic activity surpasses other catalysts. But it’s easy to absorb moisture in the air.

Packing and storage: The product is kept sealed in the polyethylene container, NW 20 kg; the product is kept vacuum in the aluminum-plastic composite bag, NW 25kg, Every 36 barrels are palletized according to the international standard, NW 720 kg or 40 barrels, NW 1000 kg.
