HPMC is widely used in building materials, coatings, synthetic materials, ceramics, medicine, food, textile, agriculture, cosmetics, tobacco and other industries. Domestic HPMC is practically building grade. In building grade, putty powder is used In a large amount, about 90% of which is used for putty powder, and the rest is used for cement mortar and glue.
The content and viscosity of hydroxypropyl group are two indicators that most users are concerned about. High hydroxypropyl content, water retention is generally better. Viscosity, water retention, relative (rather than absolute) is better, and viscous, better in cement mortar.
HPMC is a natural polymer cellulose made by a series of chemical treatments . Water-soluble white powder . It has thickened , adhesion , dispersion , emulsification , film formation , suspension , adsorption , gel and protective colloid surface activity , and retains moisture and other characteristics .
HPMC is odorless, tasteless,non-toxic cellulose ethers produce from natural high molecular cellulose through series of chemical processing and achieved.It is white powder with good water solubility. It has thickening, adhesion ,dispersing, emulsifying, film, suspended, adsorption, gel,and protectiv
