Hydroxypropyl methyl cellulose, also known as hypromellose, cellulose hydroxypropyl methyl ether, is obtained by selecting highly pure cotton cellulose as raw material and specially etherified under alkaline conditions. Widely used in construction, chemical, pharmaceutical and other industries.

construction industry
1. Cement mortar: improve the dispersibility of cement-sand, greatly improve the plasticity and water retention of mortar, and effectively prevent cracks and enhance the strength of cement.
2. Tile cement: Improve the plasticity and water retention of the pressed tile mortar, improve the bonding force of the tiles, and prevent pulverization.
3. Coating of refractory materials such as asbestos: as a suspending agent, a fluidity improver, and also to improve the bonding force to the substrate.
4. Gypsum coagulation slurry: improve water retention and processability, and improve adhesion to the substrate.
5. Joint cement: added to the joint cement for gypsum board to improve fluidity and water retention.
6. Latex putty: Improve the fluidity and water retention of putty based on resin latex.
7. Stucco: As a paste instead of natural materials, it can improve water retention and improve the bonding force with the substrate.
8. Coating: As a plasticizer for latex coatings, it has a role in improving the operational performance and fluidity of coatings and putty powder.
9. Spray coating: It has a good effect on preventing cement-based or latex-based spraying only material filler from sinking and improving fluidity and spray pattern.
10. Secondary products of cement and gypsum: It is used as the extrusion molding binder for hydraulic substances such as cement-asbestos, which can improve the fluidity and obtain uniform molded products.
11. Fiber wall: It is effective as a binder for sand walls due to its anti-enzyme and anti-bacterial effects.
12. Others: It can be used as a bubble retainer for thin mortar and plasterer operators (PC version).

chemical industry
1. Polymerization of vinyl chloride and vinylidene: As a suspending stabilizer and dispersant during polymerization, it can be used together with vinyl alcohol (PVA) hydroxypropyl cellulose (HPC) to control particle shape and particle distribution.
2. Adhesive: As the adhesive of wallpaper, it can usually be used together with vinyl acetate latex paint instead of starch.
3. Pesticides: when added to pesticides and herbicides, it can improve the adhesion effect during spraying.
4. Latex: improve the emulsification stabilizer of asphalt latex, and the thickener of styrene-butadiene rubber (SBR) latex.
5. Binder: used as a molding adhesive for pencils and crayons.

Cosmetics
1. Shampoo: Improve the viscosity of shampoo, detergent and detergent and the stability of air bubbles.
2. Toothpaste: Improve the fluidity of toothpaste.

food industry
1. Canned citrus: to prevent whitening and deterioration due to the decomposition of citrus glycosides during storage to achieve the effect of preservation.
2. Cold food fruit products: add to sherbet, ice, etc. to make the taste better.
3. Sauce: as an emulsifying stabilizer or thickening agent for sauces and ketchup.
4. Coating and glazing in cold water: It is used for frozen fish storage, which can prevent discoloration and deterioration of quality. After coating and glazing with methyl cellulose or hydroxypropyl methyl cellulose aqueous solution, it is then frozen on ice.
5. Adhesives for tablets: as a molding adhesive for tablets and granules, it has good adhesion “simultaneous collapse” (rapidly melted, collapsed and disperse when taking it).

Pharmaceutical industry
1. Encapsulation: The encapsulating agent is made into an organic solvent solution or an aqueous solution for administration tablets, especially the prepared granules are spray-coated.
2. Retarder: 2-3 grams per day, 1-2G feeding amount each time, the effect will be shown in 4-5 days.
3. Eye drops: Since the osmotic pressure of methyl cellulose aqueous solution is the same as that of tears, it is less irritating to the eyes. It is added to the eye drops as a lubricant for contacting the eye lens.
4. Jelly: as the base material of jelly-like external medicine or ointment.
5. Impregnation medicine: as thickening agent and water-retaining agent.

Kiln industry
1. Electronic materials: As a ceramic electric sealer, an extrusion-molded binder for ferrite bauxite magnets, it can be used together with 1.2-propanediol.
2. Glaze: Used as a glaze for ceramics and in combination with enamel, it can improve the bondability and processability.
3. Refractory mortar: added to refractory brick mortar or pouring furnace materials to improve plasticity and water retention.

Other industries
1. Fiber: used as printing dye paste for pigments, boron-based dyes, basic dyes and textile dyes. In addition, in the corrugation processing of kapok, it can be used together with thermosetting resin.
2. Paper: used for the surface glue and oil-resistant processing of carbon paper.
3. Leather: used as final lubrication or one-time adhesive.
4. Water-based ink: added to water-based ink and ink as a thickener and film-forming agent.
5. Tobacco: as a binder for regenerated tobacco.
