Dibenzoylmethane (DBM), with the CAS number 120-46-7, is a versatile organic compound that plays a critical role in various industrial applications, most notably as a PVC heat stabilizer. As a prominent chemical manufacturer and supplier, we aim to provide a deep understanding of DBM’s properties, synthesis pathways, and its significant industrial utility.

Chemically, Dibenzoylmethane is a beta-diketone, characterized by its molecular formula C15H12O2 and a molecular weight of 224.25 g/mol. It typically appears as a white to yellowish crystalline powder, with a melting point range of 76-80°C. Its chemical structure, featuring two phenyl rings flanking a propane-1,3-dione core, contributes to its ability to chelate metal ions and absorb UV radiation. This inherent UV absorption capability makes it an effective light stabilizer, protecting polymers from photodegradation.

The synthesis of Dibenzoylmethane often involves the condensation of ethyl benzoate with acetophenone, a common method in organic chemistry for forming beta-diketones. These well-established synthesis routes, executed in our advanced manufacturing facilities, ensure a high-purity product that meets stringent industry standards. For businesses looking to buy Dibenzoylmethane, understanding these production processes underscores the quality and reliability they can expect from our supply.

In the plastics industry, DBM is predominantly used as an auxiliary heat stabilizer for PVC. Its effectiveness is amplified when combined with primary stabilizers such as Calcium/Zinc or Barium/Zinc systems. DBM helps to prevent the discoloration and degradation of PVC during high-temperature processing, contributing to improved initial color, transparency, and overall product longevity. This makes it an indispensable additive for transparent PVC products like bottles, films, and sheets. Procuring DBM from a reputable Chinese supplier ensures consistent quality and competitive Dibenzoylmethane prices.

Beyond stabilization, DBM's UV absorption properties offer added value by providing long-term resistance against UV-induced degradation. This dual functionality makes DBM a cost-effective solution for enhancing the durability and aesthetic appeal of PVC products exposed to sunlight. We are committed to being a premier supplier of Dibenzoylmethane, offering technical expertise and reliable supply to meet the diverse needs of our global clientele.
