What is it: HPMC is a chemically modified cellulose polymer that is off-white in color and considered safe for human consumption. It is most commonly used as an alternative to gelatin and gluten in vegan-friendly products.

In the production of building materials, especially dry mixed mortar, cellulose ether plays an irreplaceable role, especially in the production of special mortar (modified mortar), is an indispensable and important part.

Soluble in water and most polar organic solvents and appropriate ratio of ethanol/water, propanol/water, dichloroethane, etc. Insoluble in ether, acetone, anhydrous ethanol. Dissolves in cold water into a clear or slightly turbid colloidal solution.

HPMC is widely used in building materials, coatings, synthetic resins, ceramics, medicine, food, textile, agriculture, cosmetics, tobacco and other industries. HPMC can be divided into: construction grade, food grade and pharmaceutical grade according to the application.

Generally the viscosity is proportional to the water retention viscosity under 100,000.but viscosity more than 100,000 water retention rate basically does not increase.so not viscosity more quality better.

It depends on your usage

In the mortar why people on water retention requirements are so high, water retention good mortar has what outstanding advantages, let me introduce to you, the importance of mortar water retention.

With the development of modern building constructions, cellulose ether is being widely used in cement products. Cellulose ether is formed by the etherification of cellulose or one or more etherifying agents and dry grinding. SLEO cellulose ether products include HPMC,and HEMC, multi-purpose additives widely used in cement products. Factors related to the properties of cellulose ethers are becoming a hot topic in the industry.

Modified additives such as pre-mixed mortar additives: cellulose ethers, accelerating agent, Redispersible polymer powder, air-entraining agents, early-strength agents, water-reducing agents, etc., which need to be added separately according to engineering use, greatly improve the performance of ready-mixed mortar, physical and mechanical properties.

The viscosity of HPMC has always been an important indicator that manufacturers and buyers pay attention to. HPMC viscosity is divided into high viscosity, medium viscosity, and low viscosity. Products with different viscosities are suitable for various application fields. For HPMC manufacturers, understanding the factors that affect the viscosity of HPMC will help us produce highly adapted and high-quality products. So, what are the factors that affect the viscosity of HPMC?
