dibenzoylmethane as a new pvc heat stabilizer, high transmittance, non-toxic and tasteless; can greatly improve the early pvc coloring, transparency, long-term stability, and processing during precipitation and "zinc burn" and so on; widely used in medical, food packaging and other non-toxic transparent pvc products. dibenzoylmethane above can absorb 290nm ultraviolet light, while light having a stabilizing effect on pvc products can provide long-term stable performance.
