The HHR-P type is the most efficient nonionic thickener available.
All viscosity types are available in easy-dispersing form, designated R (e.g., 250 HHR).
These R materials have been treated to delay hydration of the particle and thus prevent lumping as the dry powder is added to water.
NATROSOL B grade (e.g., 250 HBR) with improved resistance to biological degradation is also available.

Benefits of NATROSOL 250 HR:
Offers very good pseudoplastic flow behaviour and wide compatibility with other materials such as emulsion polymers, natural and synthetic gums, emulsifiers, defoamers, pigments, surfactants and preservatives.
NATROSOL 250 HR gives mechanical and chemical stability.
NATROSOL 250 HR controls rheology before, during, and after application.
NATROSOL 250 HR provides very good color acceptance, color development, and viscosity retention on tinting.
NATROSOL 250 HR gives fast dispersion and easier dissolving in water.
Features of NATROSOL 250 HR:
NATROSOL has the properties of thickening, adhesion, dispersion, film formation and suspension.
When the pH of the NATROSOL water solution is between 2 and 12, the viscosity is stable.
If NATROSOL 250 HR exceeds this range, acidic or alkaline oxidative degradation will occur and viscosity will decrease.
The viscosity of the Natrasol aqueous solution decreases as the temperature increases and the viscosity can be recovered when the temperature drops to the original temperature.
If there is no high salt concentration, when the solution is heated to boiling point, no gel or precipitate is formed.
That is, natrosol is very resistant to temperature.
NATROSOL aqueous solution is a nonionic system and other water soluble polymers, surfactants, salts, etc. can be found together with.
Therefore, NATROSOL 250 HR is widely used in the daily chemical industry.
