Dibenzoylmethane Usage
1. As a new type of PVC auxiliary heat stabilizer, its transparency is high, non-toxic and tasteless.
2. It is used in combination with solid or liquid calcium/zinc, antimony/zinc and other heat stabilizers, which can greatly improve the initial coloration, transparency, long-term stability of PVC, as well as precipitation during processing and “zinc burning”.
3. Widely used in medical, food packaging and other non-toxic transparent PVC products
4. Dibenzoylmethane can absorb ultraviolet light above 290nm, and has light stabilizing effect, which can provide long-term stability performance for PVC products.
