Hydroxypropyl Methyl Cellulose Ether (HPMC)

Hydroxypropyl methylcellulose (HPMC) is a versatile non-ionic cellulose ether polymer, which has different solubility properties, surface activity, thermal gelation and compatibility depending on the degree of substitution and modification of substituent groups. HPMC is mainly used in petrochemicals, coatings, building materials, paint removers, agricultural chemicals, inks, textile printing and dyeing, ceramics, papermaking, etc. Having a high viscosity, it can lock water in and reduce the rate of evaporation, hence can be used as a water retaining agent in cement/putty.
