Hydroxypropyl methylcellulose (HPMC) is a white powder, odorless, tasteless and nontoxic, which dissolves in cold water to form a transparent viscous solution.
Hydroxypropyl methylcellulose has the functions of thickening, bonding, dispersing, emulsification, film forming, suspension, adsorption, gelation, surface activity, moisturizing and colloid protection.
Hydroxypropyl methylcellulose is widely used in building materials, coatings, synthetic resins, ceramics, medicine, textiles, agriculture, cosmetics and other industries. According to the use, HPMC can be divided into: building layer, food layer, pharmaceutical layer. At present, most of the domestic production is construction grade, and the amount of construction grade putty powder is large, about 90% is used to make putty powder, and the rest is used to make cement mortar and binder.
Cellulose ether is a non-ionic semi-synthetic polymer with water-soluble and solvent properties.
In different industrial fields, such as chemical building materials, etc., it plays a different compound role, such as: water-retaining agent, thickener, leveling, film-forming, and adhesive.
Among them, the polyvinyl chloride industry belongs to emulsifiers and dispersants, and the pharmaceutical industry belongs to binders and slow and controlled release framework materials. Because cellulose has various functions in the polyvinyl chloride industry, it has the widest application range.
