Stearoyl benzoyl methane Quick Details:

Stearoyl benzoyl methane (SBM) is an important auxiliary heat stabilizer for plastics with β-diketone structure. It can be compounded with a variety of stabilizers. Through the synergy between the components, it can effectively improve the The transparency and weather resistance of vinyl chloride products avoid precipitation and “zinc burning” during processing.

Compared with commonly used stabilizers, stearoyl benzoyl methane has good thermal stability, chemical stability and light stability, is non-toxic, odorless, and does not pollute products, so it is widely used in food and medical packaging.
