High purity atomized magnesium powder manufactured by Gena is a new product to plastic catalyst. The powder enjoys a good domestic and aboard market for its following characteristics.
1 -20 micron super fine powder can be controlled under 4 percent. It is not easy to burn. Safety is guaranteed.
2 With bigger bulk density, high percent spherical powders, small surface area and good flow characteristics, it mixes homogeneously.
3 Mg content is 99.90%min and MgO 0.5-1%. Particle size distribution is narrow. Magnesium powder is used efficiently. It lowers the costs of catalyst.
4 We can manufacture atomized magnesium powder according to LLDPE and Euro Chemical Spec
