La description

Uses: Added filler, Acid can be used for rubber products and general products, Also be used as surface coating agents, sizing agents increase the agent, is also used in powder coatings, paints, plastics, rubber, ceramics, paint, batteries, enamel and so on. Performance: Hugh White orthorhombic powder, dispersion is good, high whiteness, good leveling. Has excellent lightfastness, weather resistance and acid resistance. Has good chemical inertia and moderate surface energy, so as a function of filler has good dispersibility and affinity with other media. In the powder coatings industry, particularly effective. The relative density of 4.**4.6 do not dissolve in water, acid, alkali and other solvents, heat, acid, alkali, non-toxic, can be used for food contact products Testing items indicators Testing items indicators Specifc surface area ( cm2/g) ****0±**0 Residue on **5mesh (g/kg) 0 Average parcicle size (μm) 1.2±0.*5 BaSO4 content( %) ≥*6 True specific gravity ( g/ cm3) 4.3 PH 7.**8.5 Bulk density tapped ( g/ cm3) 1.4 whiteness *2±0.5 Moisture (%) 0.*0max Oil absorption value (g/**0g) ****5 Fe content (%) ≤0.**3 Net weight (kg) *5 Water soluble matter (%) 0.*0 Test Method: 1、 BaSo4 content was measured by the outgoing department measured 2、 Whiteness GB/T********6 standard method based on measured 3、 Moisture produced by Shanghai Precision Scientific Instrument measured moisture meter 4、 Oil absorption GB***1.****8 standard method based on measured 5、 Specific surface area of Europe and the United States by the OMEC-LS**0 laser particle size analyzer measured g 6、 The average size of Europe and the United States by the OMEC-LS**0 laser particle size analyzer measured g
