PVC Stabilizer DBM (Dibenzoyl Methane) 99% | CAS 593-85-1

• Dibenzoyl Methane (DBM) is an organic β-diketone derivative compound with the chemical formula C₁₅H₁₂O₂, appearing as a light yellow to white crystalline powder or colorless rhombic flaky crystal formed by the Claisen condensation reaction of acetophenone and methyl benzoate. In the category of chemical materials, it is a high-performance functional additive rather than a direct application product, and also serves as an important intermediate for fine chemical synthesis. In industrial classification, it belongs to β-diketone derivatives in fine chemicals, with high purity requirements and wide applicability in high-end fields such as plastic processing, cosmetics, and chemical analysis.

• Poor water solubility, easily soluble in organic solvents such as chloroform, xylene and ether, and soluble in sodium hydroxide aqueous solution, with extremely low solubility in water.
• Stable chemical properties, not easy to decompose under normal temperature and pressure, with excellent thermal stability and light stability, compatible with most common plastic additives.
• Excellent UV absorption capacity, capable of absorbing ultraviolet light above 290nm, providing effective light stabilization protection for products
• Non-toxic and odorless, meeting relevant national and international safety standards for food contact and cosmetic use, with high safety in storage, transportation and operation processes.
• Good synergistic performance, showing excellent coordination effect with Ca/Zn, Ba/Zn and rare earth stabilizers, effectively inhibiting the "zinc burning" phenomenon in PVC processing.

• Dibenzoyl Methane (DBM) is commonly used in:
  
  
• Plastic processing industry (as an auxiliary heat stabilizer and light stabilizer for PVC and ABS resins, used in the production of non-toxic and transparent PVC products such as mineral water bottles, sheet materials and film products).
• Fine chemical synthesis (as an intermediate for the synthesis of high-efficiency herbicides and rare earth organic complex fluorescent materials).
