Hydroxypropyl methyl cellulose is a kind of non-ionic cellulose mixed ether. It is a semi - synthetic, inactive, viscoelastic polymer, often used as a lubricant in ophthalmology, or as an adjuvant or excipient in oral medicine, and is common in various kinds of commodities.
HPMC is a non-ionic cellulose ether made from natural high polymer cellulose by a series of chemical processing. It's an odorless, tasteless and non-toxic white powder. Dissolving it in cold water will form a transparent and thick solution. it possesses many attributes such as thickening, binding, dispersing, emulsifying, film forming, suspending, absorbing, gelling, surface activity, water maintaining and protective colloid properties.
Granularity:The passing rate of 100 mesh is more than 98.5 %; 80 mesh pass rate 100 %. The particle size of the special specification is 40 - 60 meshes.
Carbonization temperature:280-300℃
Apparent density:0.25 - 0.70 g / cm ( usually around 0.5 g / cm ) with a specific gravity of 1.26 - 1.31.
Color change temperature:190-200℃
Surface tension:The 2 % aqueous solution is 42 - 56 dyn / cm.

Chemical Name: Hydroxy Propyl Methyl Cellulose
CAS NO.: 9004-65-3 Abbreviation: HPMC MHPC
Industries: Construction, Coating, Paints, Detergent
HPMC is white powder or granule made from highly pure cotton - cellulose by reaction of etherification. HPMC is characterized by water solubility, water retention, nonionic, stability of the PH value, surface activity, temperature reversible gelling properties, thickening property, film formability, lubrication property etc.,without any organs of animals, fat and other bioactive constituents.
Our hpmc cellulose are most commonly used as performance additives in gypsum-based or cement-based construction materials. They act as water retention agent, thickener, binder and film former.
Gypsum based construction materials usually include Gypsum based plaster, Gypsum filler/joint filler, Gypsum adhesive.
Cement based construction materials usually include Tile cement mortar/tile adhesive, Plaster/render, Tile grout, Self leveling compound, Masonry mortar, External wall insulation.
Application:
Water based paints
Wall putty
Dry mixed mortar
Tile adhesive
Cement renders/ mortar
Gypsum based plaster
Exterior Insulation and Finish system(EIFS)
