Stability: Stable. Incompatible with strong oxidizing agents.
Uses antineoplastic
Uses 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.
