Precipitated Barium Sulfate ( Barite, Coating ) Una.1250 Character: Precipitated barite is the white orthorhombic crystals, for the appearance of the white powder who has good dispersion, highly whiteness, excellent lightfastness, weatherability and acid-resistant. It has an outstanding fire retardant, electric insulation, chemical inertness and middle surface area. Make it as functional filler and pigment which has good dispersive and affinity with other media. Application: - Powder coatings It can be applied into coating, paint, marine paint, car paint and latex paint, architectural coatings as improve product's chemical and electrochemical corrosion and product's decorative effects. Enhance the impacting strength of coating products.- Fillers To be used in rubber tires, rubber, plastic sheet, tape, engineering plastics products are not easy to enhance the aging series of agents. Also can significantly improve surface smoothness, reduce production costs.- Functional materials To be used in papermaking materials (mainly for paste products), flame-retardant materials, X-defense materials, battery cathode materials. It's an indispensable and important component of concerned materials which able to demonstrate the unique properties.Packing: PP/woven bag,Precipitated Barium SulfatePackage Kg/ BagBaSO4 %Whiteness105oC Loss on weight %PHOil absorption g /100gFe content %Average particle umWater absorption %Heavy MetalUna.17825≥98.0≥93.00.306.5-9.015-30≤0.004≤10.0≤0.30-Una.1250A25≥98.0≥98.00.307.0-9.015-25≤0.002≤1.0≤0.20-Una.1250B25≥98.0≥98.00.307.0-9.015-25≤0.002≤0.8≤0.20-Una.300025≥98.5≥98.50.307.0-9.015-25≤0.005≤0.6≤0.15-Una.6000Barite Powder/ LumpPackage Kg/ BagBaSO4 %Whiteness105oC Loss on weight %pHOil absorption g /100gFe content %Average particle umWater absorption %Heavy MetalPJ.40025≥90.0≥88.00.306.5-8.5100.040.1PJ.60025≥91.0≥91.00.306.5-8.5100.040.1PJ.125025≥92.0≥93.00.306.5-8.5100.040.1
