Hydroxypropyl methylcellulose (HPMC) properties:


The product combines many physical and chemical properties to become a unique product with multiple uses. The various properties are as follows:

(1) Water retention: It can retain moisture on porous surfaces such as wall cement boards and bricks.

(2) Film formation: It can form a transparent, tough and soft film with excellent oil resistance.

(3) Organic solubility: The product is soluble in some organic solvents, such as an appropriate proportion of ethanol/water, propanol/water, dichloroethane and a solvent system composed of two organic solvents.

(4) Thermal gelation: The aqueous solution of the product will definitely form a gel when heated, and the formed gel will turn into a solution again after cooling.

(5) Surface activity: Provide surface activity in the solution to achieve the required emulsification and protective colloid, as well as phase stabilization.

(6) Suspension: It can prevent solid particles from settling, thus inhibiting the formation of sediments.

(7) Protective colloid: It can prevent droplets and particles from coalescing or condensing.

(8) Adhesion: used as an adhesive for pigments, tobacco products, and paper products, with excellent properties.

(9) Water solubility: The product can be dissolved in water in different amounts, and its maximum concentration is only limited by the viscosity.

(10) Nonionic inertness: The product is a nonionic cellulose ether and does not combine with metal salts or other ions to form insoluble precipitates.

(11) Acid-base stability: suitable for use within the pH range of 3.0-11.0.

(12) Tasteless and odorless, they are not affected by metabolism; used as additives in food and medicine, they will not be metabolized in food and will not provide calories.
