Good and Poor Water-Holding Capacity of Hydroxypropyl Methyl Cellulose  A Distinction Between Good and Poor Water-Holding Capacity of Hydroxypropyl Methyl Cellulose The water-holding capacity of methyl cellulose ethers under high temperature conditions is an important indicator to distinguish the quality of methyl cellulose ethers. The factors such as the air temperature, the temperature and wind.. read more →

Properties of Hydroxypropyl Methyl Cellulose Salt Tolerance As Hydroxypropyl Methyl Cellulose is also a non-ionic ether, so it will not be ionized in the medium of water, unlike other ionic cellulose ethers, such as Sodium carboxymethyl cellulose, which shall react with the metal ions to precipitate in the solution. Adding a certain amount of salt.. read more →

Other Properties of Hydroxypropyl Methylcellulose   1. Hydroxypropyl Methylcellulose has thermal gelation property, that is, it has the excellent of being soluble in cold water but insoluble in hot water. As long as it is put in cold water, with stirring, it can be completely dissolved into a transparent solution. Products of some grades are.. read more →

Effects of Hydroxypropyl Methyl Cellulose(HPMC) in Dry Mortar in Construction   Molecular Formula of Hydroxypropyl Methyl Cellulose(HPMC): [C6H7O2(OH)3-m-n(OCH3)m,OCH2CH(OH)CH3]n]x   1. Hydroxypropyl Methyl Cellulose is easily soluble in cold water but difficult to be soluble in hot water. However, its gelling temperature in hot water is significantly higher than that of methyl cellulose (MC). And compared with.. read more →

Application Areas of Hydroxy Propyl Methyl Cellulose   Methyl cellulose, Hydroxypropyl Methyl Cellulose, hydroxypropyl cellulose and carboxymethyl cellulose are allowed as food additives in the United States, the European Union and many other countries.

Properties of  HPMC (Hydroxypropyl MethylCellulose) Hydroxypropyl MethylCellulose is a non-ionic cellulose ether, in the appearance of white powder, odorless and tasteless. It is soluble in water, most polar organic solvents, and the appropriate proportion of ethanol/water, propanol /water and dichloroethane, but insoluble in diethyl ether, acetone, and anhydrous alcohol. In cold water, it will swell into.. read more →

Solubility of Hydroxypropyl Methylcellulose (HPMC)   Because Hydroxypropyl Methylcellulose (HPMC) does not dissolve in hot water, in the initial stage, Hydroxypropyl Methylcellulose can be evenly dispersed in hot water, and then it rapidly dissolves when cooled. Two typical methods are described below.   1). Put the required amount of hot water into the container, and heat.. read more →
