Dibenzoylmethane is a β-diketone compound, appearing as a pale yellow to white powder or crystal at room temperature. It is a key component of environmentally friendly calcium-zinc heat stabilizers for PVC, effectively absorbing and replacing hydrogen chloride generated during PVC decomposition to inhibit its autocatalytic degradation, significantly improving the initial color stability of PVC products during high-temperature processing. In addition to being a primary heat stabilizer, it is also used as a UV absorber, photoinitiator, and metal ion chelating agent, widely applied in the plastics, coatings, and cosmetics industries. As the standard leader, its national standard was primarily drafted by Jiaxian Shares.
