physicochemical properties
Sex type : This product is a white or slightly yellow powder, odorless, tasteless, non-toxic and.
Soluble solution : due to contain a certain amount of hydrophobic methoxy, this product can be dissolved in some lattice into the solvent, can also be dissolved in water and organic matter mixed solvent. This product can be dissolved in cold water, to form a transparent viscous solution.
Salt resistance : due to the goods is non ionic and non polymeric electrolyte, therefore it in a metal salt or organic electrolyte aqueous solution is more stable.
Thermal gelation : when heated to a temperature above the aqueous solution of the goods can be opaque, precipitation, so that the solution to lose viscosity. But it is gradually cooling after into the original solution state. Condensation and precipitation of temperature depends on the type of product, solution concentration and the heating rate.
Water retention properties : This product is hydrophilic and its aqueous solution is a high viscosity. WIP in maintaining Gao Bao water.
Lubrication : This product can reduce the coefficient of friction and lubrication products.
Film: This product can generate strong flexible, transparent sheet, good resistance to oil ester properties.
PH stability : This product is water solution viscosity in PH3.0 - 11 range are relatively stable.
Surfactant : This product is water solution with surfactant, which has emulsifying effect, a protective colloid and relative stability.
Shape preserving : and other water-soluble polymers compared to the product solution has special viscoelastic properties.
