Dibenzoylmethane (DBM) is a typical β-diketone organic compound with excellent complexing ability, photostability, and chemical stability. Due to the presence of active hydrogen and a conjugated system in its molecular structure, DBM is widely used in polymer materials, plastic additives, UV stabilizers, organic synthesis, and the preparation of metal complexes.
In the plastics industry, dibenzoylmethane is often used as an auxiliary heat stabilizer and light stabilizer for PVC, significantly improving the material's heat resistance and weather resistance.
