active zinc oxide (ZnO) ISO9001

Rubber grade Our company produces the active zinc oxide of the low cadmium, low lead and superfine fine powder product; the rubber special-purpose product easy to disperse in the rubber or the emulsion. The other nature is similar with zinc oxide. (1)Mainly used as the rubber or electric cable's strengthening agent (intensifier), enabling the rubber to have the good nature against-erosive and anti-tearing, and have a good elasticity. (2)Also used as the natural rubbers curing activator, the white rubber's coloration and padding. (3)In addition, it is the vulcanizing agent of Chloroprene rubber. (4)It is also available in being the light stable agent of the plastic like PVC and so on. The product that is special for Petrochemical sweetening agent has a better activeness and bigger specific surface area.
