Dibenzoylmethane (DBM) is an important light stabilizer and heat stabilizer for thermoplastics with β-diketone structure. It is non-toxic, odorless, white or light yellow crystalline powder, and is widely used in polyvinyl chloride. (PVC) plastic and acrylonitrile-butadiene-styrene (ABS) resin, as a new auxiliary stabilizer for plastic processed products, easily soluble in ether, chloroform, xylene, toluene and sodium hydroxide aqueous solution, slightly soluble in Ethanol, very slightly soluble in water.

Technical Parameter

Application

1.Dibenzoyl Methane For Plastic Heat Stabilizer can absorb ultraviolet light above 290nm, has high transmittance, is non-toxic and tasteless. It can be used with solid or liquid calcium/zinc, barium/zinc and other heat stabilizers to improve the initial coloring performance, transparency and long-term stability of PVC, effectively improve the "zinc burning" phenomenon in the processing of PVC products, promote the upgrading of calcium/zinc composite stabilizers, and is widely used in the manufacture of PVC mineral water bottles, infusion sets Infusion tubes, children's toys and other medical, food packaging and other non-toxic transparent PVC products.

2. It is used for reagent analysis, determination of carbon disulfide and thallium, gravimetric determination of uranium, photometric determination of U+4, and extraction of silver, aluminum, barium, etc.

3. It is widely used in the fields of synthesis of highly effective herbicides, synthesis of ultraviolet absorbers, cosmetics sunscreen agents, synthesis of highly effective rare earth organic complex fluorescent materials, etc.
