Hydroxypropyl methylcellulose, abbreviated as HPMC, is a variety of nonionic cellulose mixed ethers. It is a semi-synthetic, inactive, viscoelastic polymer that is often used in ophthalmology as a lubricant or as an excipient or excipient in oral medications and is found in a wide variety of commodities.
In addition, as a food additive, hypromellose can play the following roles: emulsifiers, thickeners, suspending agents, and animal gelatin substitutes.
HPMC is a highly pure cotton cellulose as raw material, under alkaline conditions by special etherification and preparation.White or whitish powder.HPMC decreases with the decrease of methoxide content, increase of gel point, decrease of water solubility and decrease of surface activity.
Introduction of Landcel HPMCThe alias of Hydroxypropyl methyl cellulose is hypromellose; cellulose hydroxypropyl methyl ether, English abbreviation: HPMC, It uses cotton cellulose as raw material, and is produced by special etherification under alkaline conditions , the whole process is completed un
Tile adhesives are cement and/or polymer dispersion-based systems. The rheological additives used for these are mainly cellulose ethers, which provide the right consistency for the application, sag resistance of wall tiles, water retention for the optimum hardening of cement, and the control of open
