Pharmaceutical grade Hydroxypropyl Methyl cellulose
HPMC is widely used as an excipient in pharmaceuticals during recent years. The usage of HPMC improves the quality of some kinds of tablets. The aqueous solution or alcoholic solution of HPMC, as adhesives, could form a thin film on the appearance of the particles, which will be good for the stability of the medicine. It is especially used in the unstable medicine. HPMC has the property of surface activity, which could improve the dissolutive speed of some indissolvable medicine. Besides, HPMC also has a good film-forming property. The formed film could improve the stability of medicine and protect the tablets from discoloring.
HPMC(Hydroxypropyl methyl cellulose)
Vamcell® HPMC (hydroxypropyl methyl cellulose)
Vamcell ® Hydroxypropyl methyl cellulose is made by propylene oxide, methyl choride 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 cellulolse is turned into water-soluble nonionic polymer. Hydroxyproypl methyl cellulose is a good film-former and varies somewhat in physical and chemical properties. Hydroxypropyl methyl cellulose is quite hydrophilic and readily soluble in cold water.
For Tile Adhesive
As a kind of functional decorative material, ceramic tiles are always applied widely in the world. In order to fix tiles on substrate securely, modern thin-bed mortar is becoming widely used, multi-functional approach to tiles providing extended installantion time, greater flexibility and strong adhesion.
VAMCELL® Cellulose Ethers for Tile Adhesive provide:
♦ Excellent wetting property
♦ Excellent green adhesive bond strength on different substrates, including plywood.
♦ Increased plastic behavior and flexibility
♦ Increased cohesive force
♦ Excellent open time and sag resistance
