Application of Hydroxypropyl Methyl Cellulose (HPMC) in Building Materials
Application of Hydroxypropyl Methyl Cellulose (HPMC) in Building Materials Hydroxypropyl methylcellulose (HPMC) is made from natural polymer material cellulose. A nonionic cellulose ether produced by a series of chemical processing. And they are an odorless, tasteless, non-toxic white powder. Swell in cold water into a clear or slightly turbid colloidal solution. Therefore, it has the […]
The bastic intro of hec and hpmc
The bastic intro of hec and hpmc HEC HEC is made from refined cotton after alkali treatment, in the presence of acetone, using ethylene oxide as ether agent for reaction. The degree of substitution is generally 1.5 ~ 2.0. It has strong hydrophilic and is easy to absorb moisture. It is soluble in cold water […]
