Titanium Dioxide Specifications: HS Code:3206111000 Rutile Titanium Dioxide (Normal Use)Surface treatment: Silicon, Aluminium and Organic Index Name: Grade one TiO2% min: 92.50% Rutile conversion rate min: 97% Color (compared with sample) Not lower Whiteness min: 96 Achromaticity (compared with sample),% min: 100 Dispersiom (hagerman number) min: 6.0 105 centidegree volatile matter, % max: 0.5 Sileve residur per 45um mesh, % max: 0.02 Water solubles, % max: 0.5 PH of suspension solution: 6.5-8.5 Oil absorption g/100g max: 22 Application: TiO2 is also an effective opacifier in powder form, where it is employed as a pigment to provide whiteness and opacity to products such as paints, coatings, plastics, papers, inks, foods, medicines (i.e. pills and tablets) as well as most toothpastes. In paint, it is often referred to offhandedly as "the perfect white", "the whitest white", or other similar terms. Opacity is improved by optimal sizing of the titanium dioxide particles. Used as a white food colouring, it has E number E171. Titanium dioxide is often used to whiten skimmed milk; this has been shown statistically to increase skimmed milk's palatability.
