HPMC is widely used in building materials, coatings, synthetic materials, ceramics, medicine, food, textile, agriculture, cosmetics, tobacco and other industries. Domestic HPMC is practically building grade. In building grade, putty powder is used In a large amount, about 90% of which is used for putty powder, and the rest is used for cement mortar and glue.

The content and viscosity of hydroxypropyl group are two indicators that most users are concerned about. High hydroxypropyl content, water retention is generally better. Viscosity, water retention, relative (rather than absolute) is better, and viscous, better in cement mortar.

Hydroxypropyl methyl cellulose is propylene glycol ether of methyl cellulose, hydroxypropyl and methyl combine with anhydrous glucose ring by ether bond.It is white or pale white cellulose powder or particles. The characteristics of cold water dissolution and hot water insoluble are similar with methyl cellulose. Solubility in organic solvents is superior than water soluble, can be dissolved in anhydrous methanol and ethanol solution, also soluble in chlorinated hydrocarbons and ketones in organic solvents.

Soluble in water, its water solution has a surface activity, the formation of the film after drying, heated and cooled, in turn, from the reversible conversion of sol to gel.
