Detailed Product Description
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.
