New non-toxic auxiliary heat stabilizer of calcium, zinc and rare earth
——Dibenzoylmethane（DIBENZOYL METHANE）
 

Stearoyl benzoyl methane products: PVC new non-toxic auxiliary heat stabilizer，can be used with and calcium/zinc, barium/zinc and rare earth elements，tested by the National Research Center and proved the quality of the products fully meet the quality standards of similar foreign products. 

This product is white or light yellow crystalline powder, easily soluble in ether, trichloromethane, o-Xylene, toluene and aqueous sodium hydroxide，slightly soluble in ethanol, extremely slightly soluble in water.

As a new type of PVC auxiliary heat stabilizer, its transmittance is high, non-toxic and tasteless; it can be used with solid or liquid calcium/zinc, barium/zinc and other heat stabilizers, can greatly improve PVC initial coloring, transparency, and long-term stability, as well as the precipitation and 'zinc fever' in processing；its characteristic is it has very good synergistic effect to 'zinc soap', addition of this product can effectively inhibit 'zinc burning'，suitable to implement in rigid, non-toxic, tasteless field, promote the upgrading of the Calcium/Zinc compound stabilizer, it is widely used in medical, food packaging and other non-toxic transparent PVC products (such as PVC bottles, sheets, a transparent film etc.).

Dibenzoylmethane can absorb more than 290nm UV, at the same time having the function of light stabilization, can provide long-term stability on PVC products.
