CAS No 120-46-7 Heat Stabilizer Dibenzoyl Methane

Dibenzoyl methane dbm (also known as 1,3-diphenyl-1,3-propanedione, English name is Dibenzoyl Methane, abbreviated as DBM) is an important β-diketone structure thermoplastic for light Stabilizer, heat stabilizer, non-toxic, odorless, white or light yellow crystalline powder, widely used in polyvinyl chloride (PVC) plastic and acrylonitrile-butadiene-styrene (ABS) resin, as plastic processed products A new type of auxiliary stabilizer, easily soluble in ether, chloroform, xylene, toluene and sodium hydroxide aqueous solution, slightly soluble in ethanol, very slightly soluble in water. use 1. Dibenzoyl Methane For Plastic Heat Stabilizer can absorb ultraviolet light above 290nm, has high light transmittance, is non-toxic and tasteless. It can be used together with solid or liquid calcium/zinc, barium/zinc and other heat stabilizers to improve the initial coloration of PVC. Performance, transparency and long-term stability, effectively improve the "zinc burning" phenomenon in the proce…
