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 →
Ethyl Cellulose The ethyl groups of ethyl cellulose and its mixed ethers have stronger hydrophobicity than the methyl groups of methyl cellulose series products. Therefore, ethyl cellulose is in the industry a typical cellulose ether soluble in organic solvents but insoluble in water. When the degree of substitution of ethyl is between 0.7.. read more →
Physical Properties of Hydroxyethyl cellulose Hydroxyethyl cellulose (HEC) is a non-ionic cellulose ether made through a series of chemical processes, with the natural polymer celluloses as raw materials. It is odorless, tasteless, and non-toxic in the shape of white to off-white powders or granules. It can be dissolved in water to form a transparent.. read more →
