Sodium Sulfate Anhydrous

Sodium sulfate, also known as sodium sulfate anhydrous, is a fine crystal or powder. Sodium sulfate is an important raw material for the manufacture of glass and paper. It is largely used in the papermaking and cellulose industries

SYNONYM:Sodium Sulphate Anhydrous
CAS NO:15124-09-1
CHEMICAL FORMULA.:Na2SO4
GRADE:Tech grade
PURITY:99%
ORIGIN:China

Sodium sulfate is a component of synthetic detergents. It is a neutral salt. Adding it can reduce the surface tension and increase the solubility of detergents. It is also used as a diluent for dyes and an auxiliary for dyeing and printing, as an accelerator for dyeing cotton fibers with direct dyes, sulfur dyes, and vat dyes, and as a retarding agent for direct dyeing of silk.
