Hydroxypropyl methyl cellulose ether
As a nonionic cellulose mixed ether with excellent performance, HPMC has good dispersing, emulsifying, thickening, bonding, water retention and glue retention properties as other cellulose ethers (such as CMC, MC, HEC, MHEC, HEMC, HBMC). It is soluble in water, also soluble in ethanol and acetone below 70%. It can be widely used as thickener and adhesive.HPMC has thickening, dispersing and emulsifying film-forming properties, and is widely used in petrochemicals, building materials, ceramics, textiles, daily-use chemicals, synthetic resins, coatings and electronics and other industrial fields.
HPMC is a partially methyl and partially polyhydroxypropyl ether of cellulose, which is obtained by alkalizing cellulose and then reacting it with two etheric agents, chloromethane and propylene oxide .
