Predominance: the flakes(thickness:1mm-2mm) ,less impurity and higher content of NaHS, lower iron.
Predominance:mainly used by mill run, pesticide, dye ,leather production and organic compound. compared with other company, high purity, less impurity, not easy to be intenerated,especially less iron , sodium sulfide, sodium carbonate, Insolubles impurity in water.dip-dying in the leather production , it can disperse the fibre equably. less iron insure the appearance and good quality of leather.
