Stearoylbenzoylmethane

Overview: Stearoylbenzoylmethane (SBM) is an important auxiliary heat stabilizer for plastics with a β-diketone structure. It can be compounded with various stabilizers, and through the synergistic effect of the components, it can effectively improve the transparency and weather resistance of PVC products, preventing precipitation and "zinc burning" during processing.

Applications

 

Compared to commonly used stabilizers, SBM exhibits excellent thermal, chemical, and light stability. It is non-toxic, odorless, and does not contaminate products. As a co-stabilizer in calcium/zinc hydroxyl salt stabilization systems, it is used in the manufacture of mineral water bottles, oil drums, transparent sheets, and transparent films. It is also used as an auxiliary heat stabilizer for organic PVC, primarily in conjunction with composite calcium-zinc/composite rare earth heat stabilizers, to inhibit initial coloring, prevent "zinc burning," and improve the thermal stability of PVC products.
