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 .
The production process of hydroxypropyl methylcellulose is mainly a polysaccharide-based ether product produced by alkalinisation and etherification of cotton fibres (domestic). It is not charged itself and does not react with the charged ions in the gelling material, making it stable.The price is a
Hydroxypropyl methyl cellulose is a tasteless, odorless and non-toxic white powder that dissolves in water to form a transparent, viscous liquid. Hydroxypropyl methyl cellulose with adhesion, thickening, emulsification, dispersion, film forming, adsorption, gelling, surface moisture and protective c
