Hydroxy propyl Methyl cellulose pharmaceutical USP grade (low viscosity E3 E5 E15)

Application:Perfect film coating for granule and tablets.

HPMC(white powder) play an important part in pharmaceutical grade as pharmaceutical auxiliary material.

For HPMC, the special low viscosity like 3 cps,5cps,10cps,15cps is better used in film coationg for tablets since perfect stickiness,have good pertect efforts, increased the compressive strength and reduced fragmentation. It can be mixed using with Ethyl Cellulose in coating for organic solvent, forming strong and sticky film, good for masking the taste of tablets.

Below is specification of HPMC low viscosity (E3, E5, E10,E15)3cps, 5cps, 10cps, 15cps.just difference between the viscosity.
