Product DescriptionProduct DescriptionTitanium Dioxide, also known as titanium dioxide in chemical terms, is an important inorganic chemical pigment. It possesses excellent whiteness, covering power and chemical stability, and is widely used in various fields such as coatings, plastics, papermaking, and inks. It is currently one of the best-performing white pigments in the world.There are mainly two crystal forms: rutile and anatase. The rutile form is more stable and has stronger covering power, and is thus more widely applied; the anatase form has better whiteness, but poorer weather resistance. It is a white powder without odor or taste, with fine texture and good dispersibility.Chemically stable, it is insoluble in water, dilute acids and organic solvents. At normal temperature, it does not easily react with other substances and can withstand acidic, alkaline, oxidative and reductive environments. Titanium dioxide of rutile type has excellent weather resistance, being able to withstand the erosion of natural factors such as ultraviolet rays and wind and rain, and maintaining stable pigment properties over a long period of time; on the other hand, titanium dioxide of anatase type has poorer weather resistance and tends to turn yellow under sunlight.SpecificationTest ItemsRutile Titanium Dioxide (Industrial Grade)Anatase Titanium Dioxide (Industrial Grade)Food Contact GradeAppearanceWhite powderWhite powderWhite ultra-fine powderTiO2 Content (%)≥94.0≥98.0≥99.0Whiteness (compared with standard)≥98≥99≥99.5Hiding Power (g/m2)≤25≤30-Oil Absorption (g/100g)18-2225-3020-25pH Value (10% Aqueous Suspension)6.5-8.06.0-7.56.5-7.5Residue on Sieve (45μm, %)≤0.02≤0.05≤0.01Water Soluble Matter (%)≤0.5≤0.5≤0.2Heavy Metals (as Pb, ppm)≤10≤10≤5Arsenic (As, ppm)≤3≤3≤1Volatile Matter (105℃, %)≤0.5≤0.5≤0.3Packing & DeliveryIndustrial-grade titanium dioxide is usually packaged in multi-layer kraft paper bags or plastic woven bags lined with polyethylene film. The specifications are 25kg per bag and 50kg per bag. For high-end products (such as cosmetic grade and food contact grade), sealed aluminum foil bags or cardboard barrels are used for packaging to prevent contamination and moisture absorption. The packaging must indicate the product name (titanium dioxide), crystal form (anatase type / rutile type), TiO2 content, net weight, production batch number, production date, shelf life, manufacturer, product grade, and warning signs such as "moisture-proof" and "store gently".FAQ1. Are you a manufacturer or trading company?Re: We are one company integrated industry and trade. No matter the products we manufacture or trade, high quality products and competitive price always will be provided for you. 2.May I get one sample before placing order?Re: Yes, we'd like to provide sample for you. free samples(max 1Kg) are available, but freight cost will be born by customers. 3.Which payment is available for your company?Re: In order to prompt our cooperation, there are some payment methods for your choice. T/T(USD), Western union, Paypal, Credit card, Alipay all is ok. You can choose the one which is convenient for you. 4.Is there any possible to use my appointed label or package?Re: Sure. If needed, we'd like to use label or package according to your requirement. 5.How and when can I get my goods after payment?Re: For small quantity products, they will be delivered to you by international courier(DHL, FedEx, T/T, EMS, etc.) or by air.
