Chemical Components of Hydroxypropyl Methyl Cellulose

1. Physical appearance: white or off-white-colored natural powder. Cellulose manufacturers

2. Granularity the completing amount of 100 fine mesh is in excess of 98.5Percent the passing rate of 80 fine mesh is completely. Particle size of particular features is 40-60 mesh.

3. Carbonization temperature: 280-300℃

4. Apparent solidity: .25-.70g/cm (usually around .5g/cm), particular gravity 1.26-1.31.

5. Discoloration heat: 190-200℃

6. Work surface stress: 2Per cent aqueous option would be 42-56dyn/cm.

7. Solubility: Soluble in drinking water and a few solvents, for example ethanol/normal water, propanol/water, etc. inside an correct proportion. Aqueous remedies are surface lively*. High visibility, dependable efficiency, distinct specifications of merchandise have different gel conditions, solubility alterations with viscosity, the lower the viscosity, the higher the solubility, distinct features of HPMC have specific differences in overall performance, as well as the dissolution of HPMC in water is just not impacted by pH.

8. With all the decrease of methoxyl information, the gel point boosts, the water solubility reduces, along with the surface area activity of HPMC also decreases.

9. HPMC also provides the features of thickening potential, salt amount of resistance, very low ash natural powder, pH stability, drinking water maintenance, dimensional stableness, exceptional film-generating residence, and number of enzyme opposition, dispersibility and cohesiveness.

Physical attributes of hydroxypropyl methylcellulose:

Look and qualities: bright white or off-white colored fibrous or granular natural powder

Solidity: 1.39 g / cm3

Solubility: almost insoluble in absolute ethanol, ether, acetone swells right into a very clear or slightly turbid colloidal option in cold water

Steadiness: Strong is flammable and incompatible with powerful oxidizing substances.
