YH-03AFoundery Grade BentoniteIt is mainly used as molding sand adhesives in cast iron,Website: ,cast steel.It has higher content of montmorillonite,better green strength and hot strength,higher swelling property and better heat stability compared with similar domestic products. Using YH-03A can reduce the dosage of bentonite and water content of sand system, increase the intensity and flexibility of molding sand, improve ventilation, apparently improve the quality of cast,reduce waster. Technical Data: ItemYH-03AMethylene blue index g/100g≥37Green strength kpa≥120Hot strength kpa≥3.5Heat stablility 600℃1h,kpa≥20Swell index ml/3g≥90Moisture %≤12200 mesh(%pass)75µm%≥90
