Dibenzoylmethane (DBM) – UV Filter Chemical Supplier

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

USE

1. As a new type of PVC auxiliary heat stabilizer, it can absorb ultraviolet light above 290nm, has high light transmittance, is non-toxic and tasteless, and can be used together with solid or liquid calcium/zinc, barium/zinc and other heat stabilizers to improve the initial coloring of PVC Performance, transparency and long-term stability, effectively improve the "zinc burning" phenomenon in the processing of polyvinyl chloride products, promote the replacement of calcium/zinc composite stabilizers, and are widely used in the manufacture of PVC mineral water bottles, infusion sets, infusion tubes, children Toys and other medical, food packaging and other non-toxic transparent PVC products.

2. Used for analyzing reagents, testing carbon disulfide and thallium, measuring uranium by weight, measuring U+4 by photometry, and extracting silver, aluminum, barium, etc.

3. Widely used in the synthesis of high-efficiency herbicides, ultraviolet absorbers, cosmetic sunscreens, and high-efficiency rare earth organic complex fluorescent materials and other fields.
