hydroxypropyl methyl cellulose hpmc for cement tile adhesive
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.
