1, HPMC belongs to a natural raw material, low irritation, and more moderate performance, environmental protection, non-toxic and safe.
2, PH value is more stable, in the PH value of 6.0 to 9.0 range to ensure its stability.
3, better water retention, Hydroxypropyl Methyl Cellulose hydrophilic properties, added to the paste, paste, paste products can maintain high water retention effect.
4, has the role of viscosity thickening, when a small amount of increased dissolution, will form a transparent viscous solution, more stable performance, high transparency, solubility will change with the change in viscosity, when the viscosity is lower, the greater the solubility, but also to effectively improve the stability of the system flow.
HPMC Powder
5, has the role of thermal gelation, when the aqueous solution is heated, heated to a certain temperature, it will become opaque until the generation of flocculation state, resulting in the loss of viscosity of the solution, but after cooling, it will be transformed into the original solution state, the temperature at which gelation occurs is determined by the type of product, as well as the concentration of the solution, as well as the rate of the relevant.
6, water solubility and thickening properties, can quickly dissolve in cold water, deep in some organic solvents and water and organic solvents in the mixture.
7, anti-salt effect, because HPMC belongs to the non-ionic polymer, so in the organic electrolytes and metal salts in aqueous solution has a better stability.
8, can improve the surface activity, aqueous solution has surface activity, with the protection of colloids, emulsification, and relative stability, etc., the surface tension of 2% of the aqueous solution is 42-56dyn/cm.
9,Hydroxypropyl Methyl Cellulose other features, such as excellent film-forming properties and a wide range of enzyme resistance, bonding and dispersion.
