1. Hydroxypropyl Methyl Cellulose(HPMC) is a non-ionic cellulose ether made from natural polymer cellulose and made up through a series chemical processing. They are the white powder of odorless, tasteless and non-toxic, it can be swelled into clear or slightly muddy colloid solution in cold water. They have properties like thickening, bonding, dispersing, emulsifying, film, suspension, adsorption, gel, surface activity, maintaining water and protective colloid and so on.
2. Composition and chemical structure:
China supplier construction grade HPMC
3. Physical Properties:
1) Appearance: Appearance: white or off-white powder , odorless and flavorless.
2) Particle sizes: 100% pass rate in 80 mesh.
3) Carbonization temperature: 280-300℃. Color change temperature: 190-200℃
4) Apparent density: 0.43-0.50 g/mL (usually about 0.5 g/mL),specific density 1.26-1.31mL.
5) Surface tension: 42-56 dyn/cm (2% aqueous solution with 25 ℃).
6) Solubility: soluble in cold water, glacial acetic acid, ethanol, methanol and propylene glycol, slightly soluble in acetone depending on the degree of substitutions, The
solution of HPMC has surface activity, high tran***rency, 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 properties have differences with different types of HPMC and the solubility in water of HEMC is not affected by PH.
7) The higher methoxy content in HPMC, the lower gelation temperature, and the higher solubility in water and surface activity.
8) HPMC has some other characteristics, for example, thickening property, PH stability, retention of water, excellent film-forming property, good disperse and adhesion ability.
4. Applications: This grade HPMC is used as a plasticizer for latex paints, it has a role in improving |
