How cellulose ethers carry out water retention

Hydroxypropyl methylcellulose is a non-ionic cellulose ether made of natural polymer material cellulose through a series of chemical processing. They are a class of odorless, odorless, non-toxic white powders that swell in cold water as clear or slightly cloudy colloidal solutions. It has the properties of thickening, binding, dispersing, emulsifying, film-forming, suspending, adsorbing, gelling, surface-active, maintaining moisture and protecting colloids.

Excellent hydroxypropyl methylcellulose can effectively solve the problem of water retention at high temperature. In high temperature seasons, especially in hot and dry areas and thin-layer construction on the sunny side, high-quality HPMC hydroxypropyl methylcellulose is required to improve the water retention of the pulp.

High-quality hydroxypropyl methylcellulose, with particularly good uniformity, its methoxy and hydroxypropoxy groups are evenly distributed along the cellulose molecular chain, which can improve the oxygen atoms on the hydroxyl and ether bonds to associate with water. The ability to form hydrogen bonds turns free water into bound water, which effectively controls the evaporation of water caused by high temperature weather and achieves high water retention.
