Hydroxypropyl Methyl Cellulose (HPMC)

Product introduction:
This product to choose height of HPMC appeared pure cotton fiber as raw materials, in alkaline conditions made by special etherification, do not contain any animal organs and oil and other active component. It is water-soluble, the water, nonionic sex, PH value stability, surface activity, temperature reversible gelling sex, thickening, into the membranous, lubricity features.
Product physical properties:

HPMC is hot gel properties, product aqueous solution to form a gel exhalation after heating, cooling and dissolve, different specifications of products gel temperature difference. Solubility changes with viscosity, lower viscosity, solubility, the greater the different specifications of HPMC its nature has certain differences, HPMC dissolve in water from PH value influence.

Particle degree :

100 mesh passing more than 99%.
Pile of density:

0.25-0.70 g / (usually 0.5 g / or so), a proportion of 126-1.31.
Color temperature:

190 °C, carbonization temperature of 200 °C, 280-300.
Surface tension:

2% for 42-56dyn/solution cm.

HPMC with 7-hydroxy content increased, gel point drop, water solubility rise, surface activity also rise. HPMC is thickening, platoon salt sex, ash is low, the excellent film sex and widespread resistance to enzyme sex, dispersion and bonding and other characteristics.


This product is non-ionic cellulose ether, appearance of the white powder, odorless insipidity, soluble in water and most polar organic solvent. Solution a surface activity, transparency and stable performance.
