Stearoyl benzoyl methane Usage

PVC new non-toxic auxiliary heat stabilizer

Stearyl Benzoylmethane has a high transmittance, non-toxic and tasteless; and solid or liquid calcium/zinc, barium/zinc, and other heat stabilizers and can greatly improve the initial coloring of PVC, transparency, long-term stability, and processing In the precipitation and “zinc burning” and so on; it is characterized by zinc soap has a good synergistic effect, the formula added to the product can effectively inhibit the “zinc burn”, suitable for hard, non-toxic, odorless areas of implementation, promote calcium / Zinc composite stabilizer replacement, widely used in medical, food packaging and other non-toxic transparent PVC products (such as PVC bottles, sheet, transparent film, etc.).

Stearyl Benzoylmethane (SBM-50) is used as an auxiliary heat stabilizer for calcium zinc, barium zinc, and PVC stabilizer to prevent zinc burning, to solve PVC pre-coloring, and improve weather resistance, can be used for food, drug contact PVC material.




Store in a cool dry place, to prevent moisture, and heat. Do not damage the packaging when handling.
