Product Name
Zinc Stannate
Category
Heterocyclic Organic Compound
Description
Zinc Hydroxystannate and Zinc Stannate are active smoke suppressants as well as flameretardants. Their superior performance is because of their dual phase mechanism. In addition to exhibiting vapor phase action, similar to Antimony Trioxide, they also exhibit condensed phase action during which they act as excellent char promoters. The condensed phase action of Zinc Hydroxystannate and Zinc Stannate enhances the formation of a thermally stable carbonaceous layer at the expense of aromatic, volatile and flammable products. These products exhibit synergy with Zinc Borate, Ammonium Octamolybdate and Antimony Trioxide.
Application
Zinc Hydroxystannate and Zinc Stannate are effective in halogen free and halogen containing systems. Although generally, there is little difference in the effectiveness of Zinc Hydroxystannate and Zinc Stannate, the latter is the preferred additive for polymers that are processed at temperatures above 200oC.
