Product Details

Dibenzoylmethane CAS#120-46-7

Dibenzoylmethane (DB), a minor constituent of the root extract of licorice, belongs to the flavonoid family. It is a colorless rhombus flake crystal or yellowish-white powder. soluble in chlorohydrin and chloroform, soluble in sodium hydroxide solution, insoluble in sodium carbonate solution, and very slightly soluble in water. It is used as a colorimetric reagent for the determination of uranium.

Product Application Of Dibenzoylmethane CAS#120-46-7

Dibenzoylmethane is a new kind of PVC heat stabilizer, it has better transparency, nontoxic and odorless. In case of combined use with Calcium/Zinc, Barium/Zin and other heat stabilizer, it can greatly improve the initial color, transparency, long term stability of PVC, and also can improve the precipitation and “zinc burning” problem during the process. It has very good synergy with zinc soaps, and can protect the PVC color. This material can absorb UV at 290nm, which has the effect as light stabilizer and act as long term stabilizer for PVC products.
