What Is Stearoyl Benzoyl Methane with CAS 58446-52-9?
Stearoylbenzoylmethane (SBM) is an important β- Diketone structure is an auxiliary heat stabilizer for plastics. It can be combined with a variety of stabilizers. Through the synergistic action of components, it can effectively improve the transparency and weather resistance of PVC products, avoid precipitation and “zinc burning” during processing. Compared with common stabilizers, it has good thermal stability, chemical stability and light stability, non-toxic and tasteless, and does not pollute products.

Application
1.Widely used in food and medicine packaging, such as mineral water bottles, oil bottles, transparent sheets and transparent films.
2.As a co stabilizer of calcium / zinc hydroxide stabilization system, it is used to manufacture mineral water bottles, oil drums, transparent sheets and transparent films.
3.Organic PVC auxiliary heat stabilizer, mainly used in combination with compound calcium zinc / compound rare earth heat stabilizer, can inhibit the initial coloring, prevent “zinc burning” and improve the thermal stability of PVC products.
