Viscosity: 20,000- 200,000cps.
Physical and Chemical properties:1.Appearance: white or off-white granules or powder, odorless and tasteless powder.2.Carbonation temperature:280 -3003.Density: 0.25-0.70g /cm34.Temperature to change color:190 -2005.Surface tension:42-56dyn/cm at 2% solution6.Dissolubility: It can dissolve in water, and some solvent, such as alcohol/water, propanol/water. Aqueous solution with a surface-active, high level of transparency, stability performance. Different specification has different gel temperature, furthermore, the solubility will changed with their viscosity, that is the lower of the viscosity, the greater solubility.Application :The product is widely used in building construction , building materials , dispersing coating, wall paper coating ,polymerization aids, varnish remover, food , leather, food ,leather, printing ink paper and etc working as thickener, adhesive, moisture retentive agent, film former , excipient , emulsifier and so on . Furthermore, it also has a wide use in oil drilling and daily chemical industy.Package, storage and transportationPackage: Plastics-paper bag outside, lined with PVC bag.Storage :seal tightly. Exposing to the sun and rain is forbidden, to avoid absorption of moisture and contact with acid and alkali.Transportation: As common moisture-proof chemicals.
