Hydroxypropyl methyl cellulose
Hs code:3912, 900
Cas:9004-65-3
Hydroxypropyl methyl cellulose is a kind of white or slightly yellowish powder, odorless, tasteless, and non-toxic. The product can be dissolved in cold water to form a transparent viscous solution. The aqueous solution of this product has surface activity so that it has emulsification, protective colloids and relative stability. Ph stability: the aqueous solution viscosity of this product is relatively stable in the range of ph 3.0â??11.0. As the product is non-ionic, and in the preparation process can be effectively purified by washing with hot water, it has a very low ash content. Hydroxypropyl methylcellulose products can fully meet the standards for use of medicine, food, construction and personal care products.

*properties: dissolved in water and some organic solvent such as ethanol. Propyl alcohol. Ethylene chloride, the water solution is of surface activity. It is a nonionic surface active agent. Gelation temperature is different for different grades. For example, among 60rt hydroxypropyl methylcellulose, 60 is gelation temperature, namely, 2% water solution will form gelation at 60%.
Hydroxypropyl Methyl Celluloseare types of non-ionic cellulose ether, which are a powder of white to off white color, thatfunction as a thickener, binder, film-former, surfactant, protective colloid, lubricant, emulsifier and suspension and waterretention aid. In addition, there types of cellulose ethers exhibit properties of thermal gelation, metabolic inertness, enzy meresistance, low odor and taste, and PH stability. Due to the myriad of properties, HPMC is often used to substitute many other additives with lower concentration, making HPMC anincredibly efficient and effective additive in area of adhesives, construction, foods, household products, pharmaceuticals and etc.

It can be dissolved in water and some organic solvent such as ethanol,propyl alcohol,ethylene chloride,the water solution is of surface activity,It is a nonionic surface active agent,Gelation temperature is different for different grades. Applications: Chemical ingredient HPMC are widely used in food ,cosmetic and other daily use chemical lines, Typical usage as following: A. Industry grade Used as construction material such as plaster, Gypsum, renders, mortars, tile adhesives, wall putty, fillers, emulsion paints, self-leveling compounds, or used for PVC polymerization. B. Cosmetic and daily use chemical. According to properties of HPMC, it can be used as thickening agent, emulsification reagent, suspending reagent, stabilizing reagent, water retention reagent, rheological behavior reagent, Thus be used in all kinds of cosmetic, toothpaste and shampoos . Packing, storage, transportation: 25kg bags inner with PE bag. Keep dry where good ventilated, Do not wet ,and keep from sunshine when transport.
Hydroxypropyl methyl cellulose (HPMC) is a non-ionic cellulose used in building materials, which can be dissolved in hot or cold water to form a transparent solution with a specific viscosity. Normally HPMC is widely used in dry-mixed mortar industry, ceramic tile binder, external insulation system, self-leveling mortar, plastering, putty, paint and so on, it can improve construction performance, water retention performance, bond strength and sagging resistance.

Hydroxypropyl Methylcellulose (HPMC) are non-ionic cellulose ether & its derivatives that have hyrdroxyl groups on the cellulose chain substituted for a methoxy or hydroxypropyl group. HPMC is made from natural cotton linter under chemical reaction, which can be dissolved in both cold water and hot water to form a transparent solution. HPMC is used as a thickener, binder, and film former in construction, pharmaceutical, food, cosmetic, detergent, paints, adhesives, inks, PVC and various other applications.
Application: Building,Ceramic,Coating,Ink,Plastic Industry To provide excellent workability and water retention to spray and manual plasters, dry wall joint compounds, tile cements and grouts, extruded mortars under water concretes etc.

Hydroxypropyl methylcellulose (HPMC) is a non-ionic cellulose ether obtained by a series of chemical processing using natural polymer materials (purified cotton) as a raw material. HPMC is an odorless, non-toxic, odorless white powder that dissolves in cold water to form a clear, viscous solution, with good water retention, thickening, emulsification, film formation, suspension, adsorption, gelation, surface activity and protective colloids. The products are widely used in waterborne coatings, interior and exterior wall putty powder, thermal insulation mortar series and other product systems.
