Our factory is producing sulphur black br both in crystals and liquid. Esepcially our liquid sulphur black strength can be up to 100%.

Our environmental friendly liquid sulfur black: Solid content is from 50%-100%.

The color shade is similar to user requirements, viscosity is less than 80 centipoise, pH value is greater than 10.

During the using, the users do not need or use a small amount of Sodium sulfide in the dyeing process, which can greatly reduce the COD content in the sewage.

Liquid sulphur black is easy to use and can effectively reduce the crisp paper and cloth. It has high chromaticity and can significantly reduce the COD content
