Hydroxy Stearic Acid Benzoyl Methane - Reference Information
| EPA chemical substance information | information provided by: ofmpeb.epa.gov (external link) |
| Overview | stearoyl benzoyl methane (SBM) is an important β-diketone structure of plastic auxiliary heat stabilizer, it can be compounded with a variety of stabilizers, through the synergy between the components, can effectively improve the transparency of polyvinyl chloride products, weather resistance, avoid precipitation and "zinc burning" during processing ". |
| features | compared with common stabilizers, stearoyl benzoyl methane has good thermal stability, chemical stability and light stability, non-toxic and tasteless, non-polluting products, so it is widely used in food and pharmaceutical packaging, such as mineral water bottles, oil bottles, transparent sheets and transparent films. |
| Application | as a co-stabilizer of calcium/zinc hydroxyacid salt stabilization system, used in the manufacture of mineral water bottles, oil barrels, transparent sheet and transparent film, etc. organic PVC auxiliary heat stabilizer is mainly used in combination with composite calcium zinc/composite rare earth heat stabilizer, which can inhibit initial coloring, prevent "zinc burning" and improve the thermal stability of PVC products. |
