Kemgard® Molybdate Smoke Suppressants for Rigid and Flexible PVC Compounds

Kemgard® molybdate compounds are cost-effective smoke suppressants based on patented surface treatment technology. The Kemgard smoke suppressant product chemistries include zinc molybdate, calcium zinc molybdate and zinc oxide/phosphate complexes.

The Kemgard products are designed to replace more expensive bulk molybdate compounds (ammonium octamolybdate – AOM) with less expensive core/shell structures where an active phase (molybdate) is deposited on the surface of inert core particles, such as magnesium hydroxide, calcium carbonate, talc and zinc oxide.  Kemgard molybdate smoke suppressants are highly efficient and effective in rigid and flexible PVC and a myriad of other applications.
