Hydroxypropyl methyl cellulose (HPMC), is a cellulose carboxymethyl group substituted products. According to their molecular weight or degree of substitution, can be completely soluble or insoluble polymer, which can be used as a weak acid cation exchange agent, for the separation of neutral or alkaline protein. Carboxymethyl cellulose can form colloidal solution, high viscosity, adhesion, thickening, emulsifying, flow, shaped, water retention, protective colloid, film forming, acid resistance, salt tolerance, suspension and other characteristics, and the physiological harm, so it has been widely used in food, medicine, daily chemical, petroleum, papermaking, textile, construction and other fields in production.
HPMC is odorless, tasteless,non-toxic cellulose ethers produce from natural high molecular cellulose through series of chemical processing and achieved.It is white powder with good water solubility. It has thickening, adhesion ,dispersing, emulsifying, film, suspended, adsorption, gel,and protectiv
