3. Uses: Sodium Borate has been mainly used in the manufacturing high quality glass, optical glass, glaze of pottery and porcelain, glaze of enamel, detergent, bleaching agent, cleaning agents, flame retardant, rust inhibitor and caking agent. It could be also used as the carrier of the lubricant used in metal wiredrawing, the stabilizer of refractory material and skeleton former, the coated fluxing agent in metallurgy, the retarder of cement and concrete, the buffer of pH value in water system and emulsifier of paraffin.
4. Safety instructions: Toxic by ingestion, inhalation, eye and skin contact. Eye and skin contact can cause inflammation. Mouse, oral: LD50=1060mg/kg; rat, oral: LD50=1200mg/kg. Operation must be installed with rubber gloves, a respirator and eye protection by wearing protective clothing.
5. Package: Woven bag with two-layer plastic bag, 25 kg net each.
6. Storage: Store at cool, dry and ventilate. Shelf life of 12 months, if expire, still used if up to standard through retest. Sodium borate is a stable crystal under normal condition. If it was wet, it would react with water and give out heat to generate borax decahydrate. Take care of it. Don’t expose it in moist environment or environment of very big change in temperature and humidity if not it will caking. Therefore, it is necessary to ensure complete packaging.
7. Transportation: Avoid rain, moist. Don't mix with strong oxidizer.
* In addition:The company could research and develop the new products according to the special demand of our clients.
