Product Description
REACH, ROSH passed Low Smoke halogen free flame retardant agent used to rubber.

Zinc stannate (ZHS) is a white powder, non toxic flame retardant and low heat rate flame retardant. It has dual functions of flame retardancy and smoke suppression. The flame retardant effect is better than three oxidation two antimony. The application range of zinc stannate mainly depends on the operating temperature of the polymer, and zinc stannate is only used in the materials with temperature below 180 degrees. While zinc stannate is applicable to any kind of polymer in use.

It can be used as flame retardant and smoke suppressant in the processing of PU polyurethane and PVC PVC products. It is an ideal environmental protection substitute for three antimony oxide two Sb2O3 (toxic). It is generally used for export of plastic products, domestic high-end plastic products. With the improvement of living standards, the state in environmental protection requirements are gradually improved, zinc stannate products are gradually accepted by the domestic plastic products factory.


Non-toxic, safe and easy to operate;

It has flame retardant effect and smoke suppression function;

Small amount of additives, good performance;

Have a good synergy effect with halogen and filler;

No restriction on pigment compatibility;

Wide range of applications.

Main uses of zinc stannate:

Zinc stannate ZHS has been successfully used in the production of plastic products, such as insulation, building materials and coating medium. It is a new environmentally friendly inorganic flame retardant, is a reactive flame retardant, has a good flame retardant, smoke suppression effect, no lead and other heavy metals, three oxidation of two antimony direct substitute. The product can be used alone or in combination with other flame retardants, such as aluminum hydroxide / magnesium. A small amount of this product can effectively reduce the amount of aluminum hydroxide / magnesium, so as to maximize the mechanical properties of plastic products.
