Is hydroxymethyl cellulose the same as hydroxyclass propyl methyl cellulose?

Hydroxymethyl cellulose (Carboxymethyl cellulose) is forme by the hydroxyl group of the grape anhydride unit on the cellulose chain reacts. With the etherification group (chloroZ acid or ethylene oxide). Solsoluble in water, aqueous, ammonia and cellulose solutions, Colorless stereotypes insoluble in organic solutions and mineral oil;

Can be use in: sizing, calendering, thickening agent in the textile industry. Structural composition agents in the production of paper and paper plates; Reabsorption of the impurities in the synthetic cleaning agent. Flotation agent for selected copper-nickel and potassium ores; 0 mucin suspension thickener and stabilizer for drilling oil and gas wells; The adhesive composition of the wallpaper. Dry building mixture composition; Water latex paint components, etc.HPMC

Hypromellose (Cellulose) is from highly pure cotton cellulose as the raw material. Under alkaline conditions by special] etherification, without any animal organs and oils and other active ingredients. Solust in water and most polarity and an appropriate proportion of ethanol / water, propanol / water, dichloroethane, etc.. In the ether, acetone, absolute ethanol insoluble, dissolved in cold water swelling into a clear or slightly turbid colloid solution. HPMC

Aqueous solution has surface activity, high transparency and stable performance. HPMC has thermal gel properties, the product aqueous solution after heating to form a gel precipitation, and then dissolved after cooling, different specifications of the product gel temperature is different. The solubility varies with the viscosity, the lower the viscosity, the greater the solubility, the properties of HPMC of different specifications vary somewhat, and the dissolution of HPMC in water is not affecte by the PH value.
