What is Stearoyl benzoyl methane?

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.

 

Stearoyl benzoyl methane Usage

1. Compared with common stabilizers, stearoyl benzoyl methane has good thermal stability, chemical stability and light stability, non-toxic, tasteless, and does not pollute products, so it is widely used in food and medical packaging, such as mineral springs. Water bottles, oil bottles, transparent sheets and transparent films, etc.

2. Organic PVC auxiliary heat stabilizer, mainly used with composite calcium zinc/composite rare earth heat stabilizer, can inhibit the initial coloring, prevent “zinc burning” and improve the thermal stability of PVC products.
