【Product name】
Dibenzoylmethane DBM83
CAS NO: 120-46-7
Molecular formula: C₁₅H₁₂O₂
Molecular weight: 224.2546

【Product Uses】
New non-toxic auxiliary heat stabilizer for PVC

Dibenzoylmethane can absorb ultraviolet light above 290nm and has photostability. It has excellent ability to inhibit initial coloration and effectively improves the "zinc burning" phenomenon during the processing of PVC products.

Used together with calcium/zinc, barium/zinc, and rare earth elements as a new PVC auxiliary heat stabilizer, it has high light transmittance, non-toxic and tasteless; used together with solid or liquid calcium/zinc, barium/zinc and other heat stabilizers, It can greatly improve the initial coloring, transparency, long-term stability of PVC, as well as precipitation and "zinc burning" during processing; its characteristics The point is that it has a good synergistic effect with zinc soap. The addition of dibenzoylmethane in the formula can effectively inhibit "zinc burning", which is suitable for implementation in hard, non-toxic and tasteless fields, and promotes the upgrading of calcium/zinc composite stabilizers. , widely used in medical, food packaging and other non-toxic transparent PVC products (such as PVC bottles, sheets, transparent films, etc.).
