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.


It should be sealed and shaded to be stored in a dry, cool, well ventilated place.
