Hydroxypropyl Methyl Cellulose (HPMC) is a non-ionic cellulos
Hydroxypropyl Methyl Cellulose (HPMC) is a non-ionic cellulose ether prepared from a series of chemical processing using natural cotton polymer material refined cotton as raw material. It is mainly used in construction industry - dry powder building materials such as water-resistant putty powder, putty paste, steel putty, coating glue and thermal insulation mortar, etc. It has good water retention effect, easy construction, good brightness, and viscosity and gel time can be customized according to customer needs.
HPMC is a kind of small particle size nonionic Hydroxypropyl Methyl Cellulose with properties of good water retention, good batch stability, excellent thickening, water retention, workability increased, stable suspension, surface activity, lubrication etc. We are also available to supply various unmodified and modified grade of HPMC according to customers’ different request on performance or universal application fields.

Properties: This product is a kind of white or slightly yellowish powder, and it is odorless, tasteless and non-toxic.
Water-soluble and thickening ability: This product can be dissolved in cold water to form a transparent viscous solution.
Dissolution in Organic Solvents: Due to the presence of a certain amount of hydrophobic methoxyl groups, this product can be dissolved in some organic solvents, but also soluble in water and organic solvents.
Salt resistance: Because this product is nonionic and non-polymeric electrolyte, it is relatively stable in aqueous solutions of metal salts or organic electrolytes.
Surface activity: The aqueous solution of this product is surface-active, making it emulsifying, protecting the colloid and relative stability.
Thermal gelation: When heated above a certain temperature, the aqueous solution of this product can become opaque, resulting in precipitation and loss of solution viscosity. However, it gradually turns to its original solution after cooling down. The temperature at which condensation and precipitation occur depends on the type of product, the concentration of the solution, and the heating rate.
Low ash content: Because this product is non-ionic, it can be efficiently refined with hot water during the preparation process, so its ash content is very low.
PH stability: The viscosity of the aqueous solution of this product is relatively stable in the PH3.0-11.0 range.
Water retention effect: As this product is hydrophilic and its aqueous solution is highly viscous. It is added to mortar, gypsum, paint, etc. to maintain high water retention in the product.
Shape retention: Compared with other water-soluble polymers, this product's aqueous solution has special viscoelastic properties. Its addition has the ability to improve the shape of extruded ceramic products and the like.
Lubricity: Add this product can reduce friction coefficient and improve the lubrication of extruded ceramic products and cement products.
Film formation: This product can produce strong, flexible, transparent flakes with good oil and ester resistance
