hydroxypropyl methyl cellulose

hydroxypropyl methyl cellulose(HPMC) is a type of non-ionic cellullose ether made from highly pure cotton cellulose materials through a series of chemical processes.They are odorless,tasteless non-toxic white powder in cold water swelling into a clear or slightly muddy colloid solution.

Particle size: 100 pass rate of more than 98.5%, 80 orders, 100% pass rate

Carbonization temperature: 280~300 ℃

Apparent density: the proportion of 0.25~0.70/cm 1.26~1.31

Color temperature: 190~200 ℃

Surface tension: 2% aqueous solution of 42~56dyn/cm

Solubility: soluble in water and solvent, aqueous solution with surface activity. High transparency. Stable performance, solubility varies with the change of viscosity, lower viscosity, higher solubility.

HPMC also has a thickening ability, salt tolerance, PH stability, water retention, dimensional stability, excellent film forming, and a wide range of resistance enzymes, dispersion and adhesion characteristics.

Industrial grade HPMC are mainly used as a dispersant in the production of the polyvinyl chloride, suspension polymerization for preparing PVC the main auxiliaries. In addition, in other petrochemical, paint, building materials, paint remover, agricultural chemicals, printing ink, textile, ceramics, paper, cosmetics and other products as a thickener, stabilizer, emulsifier, excipients, water retaining agent, film forming agent. Application in synthetic resin, in order to obtain products with regular particles, loose, as appropriate proportion, the characteristics of good processing performance, thus basically replaced gelatin and polyvinyl alcohol as dispersing agent.
