Birla Sodium Sulphate

Birla Sodium Sulphate, which is a rayon grade Sodium Sulphate, with a pH value of 7-9 indicates the absence of any acidity. This advantage makes sodium sulphate preferable in pulp-paper and glass industries. In the detergent industry, where sodium sulphate is consumed up to 40% by wt., the complete absence of toxic minerals and the neutral pH zone is of crucial importance.
