VAMCELL™ MHPC Hydroxy Propyl Methyl Cellulose
VAMCELL™ is our registered trademark of Hydroxy Propyl Methyl Cellulose.
Introduction
VAMCELL™ HPMC is made by propylene oxide, methyl chloride with alkali-cellulose after a chemical process called Etherification under rigidly controlled conditions. The resultant nonionic polymer is purified, dried and ground to a fine white powder, this water-insoluble cellulose is turned into water-soluble nonionic polymer, HPMC is a good film-former and varies somewhat in physical and chemical properties. HPMC is quite hydrophilic and readily soluble in cold water.

What is HPMC for gypsum
Hydroxypropyl methyl cellulose (HPMC) is a non-ionic cellulose ether obtained from cellulose after alkalinization, etherification, neutralization and washing.
HPMC for gypsum has good thickening, dispersing, emulsifying and film-forming properties, and is the first choice for producing high quality building material additives.
Properties of HPMC for gypsum
To meet the needs of environmental protection, our product has the characteristics of high water retention, good dispersibility, good fineness, good processability and easy dissolution. It is widely used in building substrates, with good water retention and improved workability. It can also prolong the opening time and improve the anti-sagging property.

It can be dissolved in water and some organic solvent such as ethanol,propyl alcohol,ethylene chloride,the water solution is of surface activity,It is a nonionic surface active agent,Gelation temperature is different for different grades.
Applications:
Chemical ingredient HPMC are widely used in food ,cosmetic and other daily use chemical lines, Typical usage as following:
A. Industry grade
Used as construction material such as plaster, Gypsum, renders, mortars, tile adhesives, wall putty, fillers, emulsion paints, self-leveling compounds, or used for PVC polymerization.
B. Cosmetic and daily use chemical.
According to properties of HPMC, it can be used as thickening agent, emulsification reagent, suspending reagent, stabilizing reagent, water retention reagent, rheological behavior reagent, Thus be used in all kinds of cosmetic, toothpaste and shampoos .
Packing, storage, transportation:
25kg bags inner with PE bag.
Keep dry where good ventilated, Do not wet ,and keep from sunshine when transport.
Hpmc may serve as thickening agent, dispersant agent, emulsifying agent or film-forming agent, and its ndustrialized products may be applicable to the production of daily chemicals, synthetic resin, construction nd coating materials.
