Hpmc Chemicals 200000 99.9% Hydroxypropyl Methyl Cellulose Manufacturer Hpmc For Construction
Product Information:
1)Appearance: HPMC is a nonionic cellulose ether, white grayish-white powder or granule,odorless and flavorless,
soluble in cold water, glacial acetic acid, ethanol, methanol and propylene glycol, slightly soluble in acetone depending
on the degree of substitutions, practically insoluble in hot water, ethylene glycol and toluene. HPMC is dissolved in a
mixture of 10% methanol and 90% methylene chloride to form colloidal solutions.
2) The solution of HPMC has surface activity, high transparency, and stable performance. When heated at certain
temperature, the solution becomes cloudy or forms flocculent gel. However, the solution becomes clear again after cooling.
Different types of HPMC have different gelation temperatures. The solubility varies with the viscosity. The lower the
viscosity, the higher solubility it has. The different types of HPMC are different in some properties and heir solubility in
water is not affected by pH.
3)HPMC has some other characteristics, for example, thickening property, pH stability, retention of water, excellent
film-forming property, good disperse and adhesion ability.
