Hydroxypropyl Methyl Cellulose

Soluble in some organic solvents and water

It can be dissolved in cold water; the highest concentration only depends on the viscosity. Solubility changes according to the viscosity, lower viscosity causes greater solubility. Some brands of products can be dissolved in binary organic solvent and organic solvent water system.

Salt resistance

Nonionic cellulosic ether product is not a polyelectrolyte, so when a metal salt or organic electrolyte exists, it is stable in aqueous solution, but excess electrolytes could cause gel and precipitation.

Surface activity

As the aqueous solution with surface activity, can be used as colloid protective agent, emulsifier and dispersant.

Thermal gelation

When product solution heated to a certain temperature, becomes opaque, gel formation of precipitation, but at the time of continuous cooling, then returned to the original solution, the gel and precipitation temperature mainly depends on their lubricant, suspending agent, protective colloid, emulsifier and so on.

Metabolism of inert and low odor and flavor

Because they are not metabolism and have low odor and flavor, so they are widely used in the food and drug.

Fungus resistance

It has a better anti-mildew ability, good stability of viscosity in long term storage.

PH stability

viscosity of aqueous solution of products is not subject to the influence of acid or base, PH value is stable in 3.0~11.0

Low ash content

Since the product is non-ionic, in the course of preparation can be washed with hot water effectively refined, so it has low ash content.

Shape

Due to the high concentration of aqueous solution compared with other polymers has special elastic property, it is added to improve the shape retention of extruded ceramic products

Water retentivity

The product has hydrophilic and high viscosity of the water solution, it is a efficient water retention agent.
