aluminium hydroxide

Aluminium hydroxide for filler (synthetic onyx)CHALCO is the world's largest producer of white hydrate and has the broadest and most flexible product range available.CHALCO has two distinct precipitaiton process that give different controlled partilcle size distribution characteristics.In addition various particle sizes are available, allowing optical characteristics, flow properties and gel properties to be controlled in order to meet user's specific requirements.A white powder, soluble in strong acid and alkali, stable under atmospheric temperature and easily decomposed into aluminium oxide by being heated. Mainly used as a filler in toothpaste, artificial onyx, low voltage isolators, a retardant filler in low voltage isolators, a retardant filler in plastics, rubber and glass-reinforced fibre.BrandChemical Composition %PHAbsorption of oil ml/100gWhitenessParticle sizeMoistureAl(OH)3SiO2Fe2O3Na2OD50+100mesh+325meshH-WF-899.60.050.020.307.5-9.833967-903 max.0.4H-WF-1099.60.050.020.307.5-9.833968-1104 max.0.3H-WF-10-SP99.60.030.020.207.5-932958-1104 max.0.3H-WF-1499.60.050.020.307.5-9.8329513-18012 max.0.3H-WF-14-SP99.60.030.020.207.5-9.8309513-18012 max.0.3H-WF-2099.60.050.020.257.5-9.8329518-25030 max.0.2H-WF-20-SP99.60.030.020.207.5-9.8309418-25030 max.0.2H-WF-2599.60.050.020.307.5-10329522-28035 max.0.2H-WF-50-SP99.60.030.020.207.5-10309340-6000.2H-WF-7599.60.050.020.207.5-10409375-9000.1H-WF-75-SP99.60.030.020.207.5-10309275-9000.1H-WF-9099.60.050.020.207.5-10309370-10000.1H-WF-90-SP99.60.030.020.207.5-10309180-11000.1
