Product Description:

Dibenzoylmethane is a white or yellow powder with a density of 1.176g/cm3 and a molar mass of 224.255. Dibenzoylmethane is a lead-free stabilizer that can be used simultaneously with other stabilizers without conflict. Because dibenzoylmethane is lead-free and environmentally friendly, it is often used in children's toys, drinking fountains, infusion tubes, etc. Dibenzoylmethane can absorb 290nm ultraviolet rays and can be used as an ultraviolet absorber, often used in sunscreen products.

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.
