What is hydroxypropyl methyl cellulose HPMC ?

Hydroxypropyl methylcellulose (HPMC) is nonionic cellulose ether prepared by a series of chemical processing using natural polymer material cellulose as a raw material. They are an odorless, tasteless, non-toxic white powder that swells in cold water into a clear or slightly turbid colloidal solution. It has the characteristics of thickening, bonding, dispersing, emulsifying, film forming, suspension, adsorption, gel, surface, moisture retention and protective colloid. HPMC, MC can be used in construction materials, coatings industry, synthetic resin, ceramic industry, pharmaceuticals, food, textile, agriculture, daily chemical and other industries.

Hydroxypropyl methyl cellulose as a white or off-white powder, soluble in water and some solvents, soluble in water and some solvents, HPMC also has thickening ability, the hydroxypropyl methyl cellulose (HPMC) into water After, the formation of transparent colloid, see the transmittance, the better the larger the transmittance, which illustrate insolubles less. Vertical reactor transparency in general are good, horizontal reactor to be satisfactory, but can not explain the quality of legislation kettle pot production would produce better than lying, there are many factors that determine the quality of products.
Hydroxypropyl methylcellulose particle size; 100 mesh pass rate of more than 98.5%; 80 mesh pass rate of 100%. Special specifications of particle size 40 to 60 mesh. HPMC apparent density: 0.25-0.70g / cm (typically 0.5g / cm or so), the proportion of 1.26-1.31. Hydroxypropylmethylcellulose color temperature: 190-200 ℃. Surface tension: 2% aqueous solution of 42-56dyn / cm. Carbonization temperature: 280-300 ℃.
Hydroxypropyl methylcellulose also have thickening ability, low ash salt, pH stability, retention, dimensional stability, excellent film-forming properties, as well as a wide range of anti-enzyme, dispersing and adhesion and so on.

1,thermal insulation mortar, ceramic tile adhesive, jointing agent, stucco gypsum, plaster;

Re:HPMC increased with methoxy content reduce, the gel point,water solubility and surface activity also declined, depends on coustomers' situation
