Property:
White crystal pellet, flavourless and non-toxicity, easy to deliquesce in damp air and excellent solubility in ethylene glycol.
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.
