Description

Hydroxypropyl MethylCellulose (HPMC)
Hydroxypropyl Methyl Cellulose (HPMC) another name is Hypromellose, it is is a natural polymfer cellulose as raw material, made of a series of chemical processing and non-ionic cellulose ether. It is white powder with good water solubility. hpmc have many properties such as thickening, adhesion, dispersing, emulsifying, film, suspended, adsorption, gel, and protective colloid properties of surface activity and maintains moisture function properties .Hydroxypropyl Methyl Cellulose are widely used in construction materials,building materials, coatings industry, synthetic resin, ceramic industry, textile, agriculture, daily chemical and other industries.
