Hydroxypropyl Methylcellulose(HPMC)

About

What is Hydroxypropyl Methyl Cellulose (HPMC)? HPMC is a non-ionic cellulose ether polymer. It is derived from cellulose, a natural polymer obtained from refined cotton linters, and is supplied as a free-flowing powder. Its specific chemical properties and advantages vary based on the degree of substitution and modification of its substituents, which result from reactions with sodium hydroxide, chloromethane, and propylene oxide during alkalization and etherification.
