Applications New-model PVC non-toxic subsidary heat stabilizer Dibenzoyl methane has

excellent coloring inhibiting performance in early stage.It can be used as new-model PVC

ubsidary heat stabilizer with calcium/zinc series, barium/zinc series, and rare earth elements;

it can greatly improve initial coloring performance, transparence, and long-term stability if

used with solid or liquid calcium/zinc, barium/zinc, and other heat stabilizers. It is widely used

in non-toxic and transparent PVC products such as pharmaceutical and food packages.


Storage    Keep in a dry, cool and well-ventilated place. Keep container tightly closed.
