HPMC(Hydroxy propyl methyl cellulose)
1, Appearance: white or kind of white powder.
2, Granularity: 100 mesh percent of pass more than 98.5%; 80 mesh passing rate is more than 100%.
3, Carbonization temperature: 280-300 °C
4, Apparent density: 0.25-0.70 / cm3 (usually in 0.5 g/cm3 or so), specific gravity of 1.26-1.31.
5, Colour temperature: 190-200 °C
6, Surface tension: 2% aqueous solution for 42-56 dyn/cm.
7, HPMC can be soluble in water and part of the solvent, such as the right proportion of ethanol/ water, propyl alcohol/water, trichloroethane, etc.
8,HPMC with methoxy content reduce, gel point rise, water solubility drops, the surface activity also declined.
9, HPMC also has the thickening ability, salt resistance low ash powder, PH stability, water retention, dimension stability, excell ent film-forming property, and a wide range of resistance to enzymatic, dispersity and caking characteristics.
Our HPMC is mainly used in the construction field.
In building construction, it is mainly used for external wall thermal insulation system, thermal insulation mortar, decoration mortar, masonry mortar and self-leveling mortar etc..
It is used as thickener, stabilizer, emulsifier, excipient, water retaining agent, film-forming agent etc.
During the decorative construction, it is mainly used for building walls, stuccoing, caulking and other mechanized construction
It can be used to paste ceramic tile, marble and plastic decoration, which is of high adhesive strength and can also reduce the amount of cement.
When used as thickener in coatings industry, it can make the coating light and delicate without taking off of powder and improve leveling performances etc..
25kg multiply paper bags with PE inner.
Storage and Shelf Life:
2 years under cool, dry conditions in original packaging away from heat sources. It is recommended to use the product in rotation on a first-in first-out basis.
