Classification: Phosphate
Type: Sodium Hexametaphosphate
Purity: 68%
Property: White powder, specific weight is 2.484(20degrees Celsius)easy to be dissolved into water, not dissolved into organic solvent, with strong hygroscopicity, it takes on mucilage glue look when gradually absorbing water in air. It can become soluble chelate complex with metal ion, like Ca, Ba, Mg, Cu, Fe. It's a refined water treantment chemical.

Application: It can be used as water softener, buffering agent, floating agent, dispersant, high temperature anchoring agent in oil field, paper-making, weaving, dyeing and printing, petrol, chemical, leather, building material. As additive, nutrition agent, quality improvement agent, pH value adjusting agent, metal ion chelating agent, adhesive, swelling agent.
