Hydroxypropyl methyl cellulose (HPMC) is a nonionic cellulose ether prepared by a series of chemical processing using natural polymer material cellulose as a raw material. Can be applied to building materials, coatings industry, synthetic resin, ceramic industry, medicine, food, textile, agriculture, daily chemical and other industries.
Construction industry：
- Cement mortar: Improve the dispersibility of cement-sand, improve the plasticity and water retention of the mortar, and have an effect on preventing cracks, which can enhance the strength of the cement.
- Tile cement: Improve the plasticity and water retention of the pressed tile mortar, improve the bonding force of the tile.
- Refractory coating: as a suspension agent, fluidity improver, but also improve the adhesion to the substrate.
- Gypsum coagulation slurry: improve water retention and processability, improve the adhesion to the substrate. .
- Others: Bubble retaining agent (PC version) that can be used as a thin clay mortar and mud hydraulic operator
Chemical industry：
- Polymerization of vinyl chloride and vinylidene: As a suspension stabilizer for polymerization, a dispersant can be used in combination with vinyl alcohol (PVA) hydroxypropyl cellulose (HPC) to control the distribution of particles and particles.
- Adhesive: As a bonding agent for wallpaper, instead of starch, it can usually be used together with vinyl acetate latex paint.
- Pesticide: added to pesticides, herbicides, can improve the adhesion effect when spraying.
- Latex: An emulsion stabilizer for improving asphalt latex and a thickener for styrene-butadiene rubber (SBR) latex.
- Binder: As a molding adhesive for pencils and crayons.
Cosmetics industry
- Shampoo: Improve the viscosity of shampoo, washing agent and detergent and the stability of bubbles.
- Toothpaste: Improve the fluidity of toothpaste.
Food industry
- Canned citrus: Prevents whitening and deterioration due to decomposition of citrus in storage.
- Cold water coating glazing: used for frozen fish storage, can prevent discoloration, quality degradation, coated with methyl cellulose or hydroxypropyl methyl cellulose aqueous solution, and then frozen on the ice layer.
- Adhesives for tablets: As a molding adhesive for tablets and granules, the adhesion “crash at the same time” (dissolving rapidly and dispersing when taken) is good.
Pharmaceutical industry
- Encapsulation: The solution is prepared into a solution of an organic solvent or an aqueous solution, and the prepared granules are spray-coated.
- Eye drops: Since the osmotic pressure of the aqueous solution of methyl cellulose is the same as that of tears, it is less irritating to the eyes, and is added as an lubricant for contact with the lens of the eyeball.
- Jelly agent: used as a base for jelly-like external use or ointment.
- Impregnating drugs: as a thickener, water retention agent.
Kiln industry
- Electronic material: As a ceramic electric relay, the binder of the ferrite bauxite magnet can be used together with 1.2-propylene glycol.
- Glaze: used as a ceramic glaze and with enamel, can improve the bonding and processing.
- Refractory mortar: added to refractory brick mortar or cast furnace material, can improve plasticity and water retention.
Other industries
- Fiber: used as a printing paste for pigments, boron forest dyes, salt-based dyes, textile dyes, and in combination with thermosetting resins in corrugated processing of kapok.
- Paper: used for carbon paper and oil resistant processing of carbon paper.
- Leather: used as the final lubrication or disposable cement.
- Water-based ink: added to water-based ink, ink, as a thickener, film-forming agent.
- Tobacco: as a binder for recycled tobacco
