HPMC is a kind of cellulose ether. It is rheology modifier and water retention agent. Because of these features, it is always used as a material of additives. Such as mortar additive, concrete additive, putty powder additive, coating additive, even ceramics additive and so on. HPMC has a really wide usage
Properties: This product is a white or kind of white powder. It is non-toxic, odorless and tasteless.
Water soluble and thickening ability: This product is soluble in cold water and come into being transparent viscous solution.
Dissolved in organic solvents: Because of containing a certain amount of hydrophobic methoxyl, this product is soluble in some organic solvent, and it can be also dissolve in water and organic mixed solvents.
Salt resistance: Because this product is non-ionic polymer, it is stable in metal salt or organic electrolyte aqueous solution.
Surface activity: The aqueous solution of this product has surface activity, it has function of emulsification, protective colloid and relatively stability.
Thermal gelation function: When the aqueous solution of the product heated to a certain temperature, it becomes opaque and turns into flocculation state with a bereft of viscosity. But after cooling, it will be transformed into the original solution state. The temperature of gel phenomenon depends on the type of product, the concentration of the solution and heating rate.
Low ash content: Because of the thermal gelation, in the process of production, it can be refined by hot water washing the products.
PH stability: The viscosity of this product's aqueous solution is stable in PH3.0-11.0.
Film-forming: This product can turns into flexible, transparent and excellent mechanical properties thin films, it has good performance of resistance to oil and grease.
