Cellulose ether, especially hydroxypropyl methyl cellulose ether (HPMC), is an important component in commercial mortar. The effects of cellulose ether on cement-based materials include water retention, thickening, air entrainment and retardation, which are excellent in giving commercial mortar. At the same time, it also affects the macro and micro structure of cement hydration products, thus affecting the mechanical properties of commercial mortar. Cellulose ethers are usually divided into two categories: surface modification and non-surface modification.

Hydroxyethyl methyl cellulose ether, referred to as HEMC, is a non-ionic cellulose ether obtained from natural polymer material cellulose through a series of chemical reactions. It is an odorless, tasteless, non-toxic white to off-white powder or granule, which can be dissolved in cold or hot water to form a transparent viscous solution, which has the functions of thickening, binding, water retention, dispersion, emulsification and film formation.

Hydroxyethyl methyl cellulose ether soluble in water and some organic solvents.  Can be dissolved in cold water, its highest concentration is determined only by viscosity, solubility changes with viscosity, the lower the viscosity, the greater the solubility.  Because the aqueous solution has surface active function, can be used as colloid protectant, emulsifier and dispersant, the highly concentrated aqueous solution of the product has special viscoelastic properties compared with the aqueous solution of other polymers, and its addition has the ability to improve the shape

HPMC(Hydroxypropyl methyl cellulose) is mainly used in the field of honeycomb ceramics. Honeycomb ceramics were first used to purify the exhaust gas of small cars. Now they have been widely used in chemical industry, electric power metallurgy, petroleum, electronics, electrical appliances, machinery and other industries. With the development of technology, more and more thin～walled honeycomb ceramics are used.

As one of the most important raw materials in tile adhesive, cellulose ether plays a crucial role in the performance of tile adhesive. The role of cellulose ether in tile adhesive is mainly manifested in thickening, water retention, delaying cement hydration, improving workability, improving anti-slip performance and rheology, plasticity and lubricating properties, extending open time, enhancing bond strength, etc.

Hydroxypropyl Methyl Cellulose products have the maximum consumption in the area of suspension polymerization of vinyl chloride in China. In the suspension polymerization of vinyl chloride, the dispersed system has a direct impact on the product, PVC resin, and on the quality of its processing and products. Hydroxypropyl Methyl Cellulose helps to improve the thermal stability of resin and control the particle size distribution(in other words, adjust PVC density), and its amount accounts for 0.025% -0.03% of PVC production.
