5,physics and chemistry nature
1, outward appearance: White or kind of white powder, not smelly tasteless.
2, granularity: 100 item capacities are bigger than 98.5%,80 item capacities are bigger than 100%.
3, carbonization temperature: 280-300oC.
4, apparent density: 0.25-0.70g/cm(usually about 0.5g/cm),proportion 1.26-1.31.
5, color deterioration temperature : 190-200oC.
6, surface tension: When 25oC,2%water-soluble fluid are 42-56dyn/cm.
7, solubility: Dissolves in the water and the part organic solvent, like suitable proportion ethanol /water, propyl alcohol/water.dichloroethane and so on. The water-soluble fluid has the surface activity high, the transparency, the performance is stable The solubility changes along with viscosity, the viscosity is lower, the solubility is bigger,different specification of HPMC its performance has certain difference. HPMC does not dissolve in the water outward appearance the PH value influence.
8, HPMC reduces along with the methoxy content, a gelatin ascension, the water solubility drops, the surface activity also drops.
9, HPMC also has dewaters ability, arranges the salinity low ash content, the PH stability, the water retention property, Excellent into the membranous,as well as widespread bears, dispersibility and cohesiveness characteristics and so on .
10,Surface activity: The HPMC water-soluble fluid has the surface activity function, may take the colloid protecting agent, the emulsifier and the dispersing agent.
11, hot gelatin: When the HPMC water-soluble fluid heats up to certain temperature, changes is not transparent, the gelatin,forms the precipitation, but when is cooling continuously, then restores to the original solution condition. But has this kind of gelatin and the precipitation temperature mainly is decided by theirs type, the density and the heating speed.
12, PH stability: HPMC water-soluble fluid viscosity nearly not acid or alkali influence, moreover the PH value quite is stable in 3.0-11. scopes. Therefore, the solution viscosity tends to stably in the standing storage process.
13, water retention property: HPMC is one kind of highly effective water retention agent. The goods in the building material, food,the cosmetics as well as other many aspects has the widespread application.
14, cohesiveness: May take the pigment, the paper bond, but also available foresees accurately in the coating and the Adhesion material.

6,Application:
It is widely used as thickener, adhesive, water preserving agent, film-forming agent in construction, building materials, dispersion coating, wallpaper paste, polymerization aids, leathers, printing ink and paper making etc. l also used in petroleum drilling and daily-use chemicals.

7, packing storage and transportation
1.25kgs net weight plastic woven bag, inner polythene bag.
2.25kgs net weight Composite paper bag, inner polythene bag. Storage on the indoor and ventilated dry place, pay attention to moisture proof. The transport process the rain proof, pay attention to bask .
