Hydroxypropyl methylcellulose (hpmc), hpmc is white or milky white, odorless and tasteless, fibrous powder or granules, the loss on drying does not exceed 10%, may be dissolved in cold water but not in warm water, slowly in warm water swells, peptizes, forms a viscous colloidal solution, cools to an answer, and for that reason turns into a gel while heated.

HPS is a kind of ionic hydroxypropyl starch ether, which is produced by a series of chemical and physical reactions with starch as raw material. It is a kind of non-toxic, tasteless white or beige power, which can be dissolved in cold water to form transparent or translucent viscous liquid. It is effective in thickening, adhesion, dispersion, emulsification, suspension, adsorption, surface activity, water retention and so on.  ETON Hydroxypropyl starch ether is a kind of chemical modified starch mainly used as thickener and texturing agent for cement or gypsum based mortar products.

HEMC are often used as water-retaining agents in (desulfurized) gypsum mortar. Years of research have shown that,water-retaining agent has a very important influence on the gypsum quality and anti-plastering layer performance of plastering gypsum.

Tile cement mortar is used to attach tiles on concrete or block walls.

HPMC(Hydroxypropyl methyl cellulose) is mainly used in the field of honeycomb ceramics. Honeycomb ceramics were first used to purify the exhaust gas of small cars. Now they have been widely used in chemical industry, electric power metallurgy, petroleum, electronics, electrical appliances, machinery and other industries. With the development of technology, more and more thin～walled honeycomb ceramics are used.

Hydroxypropyl methylcellulose (HPMC), HPMC is white or milky white, odorless and tasteless, fibrous powder or granules, the loss on drying does not exceed 10%, can be dissolved in cold water but not in hot water, slowly in hot water Swells, peptizes, forms a viscous colloidal solution, cools to a solution, and accordingly becomes a gel when heated.

Cellulose ether, especially hydroxypropyl methyl cellulose ether (HPMC), is an important component in commercial mortar. The effects of cellulose ether on cement-based materials include water retention, thickening, air entrainment and retardation, which are excellent in giving commercial mortar. At the same time, it also affects the macro and micro structure of cement hydration products, thus affecting the mechanical properties of commercial mortar. Cellulose ethers are usually divided into two categories: surface modification and non-surface modification.

Application of low viscosity hydroxypropyl methylcellulose (HPMC) in ceramics: In the ceramic industry, it is used as an adhesive for molding surprise ceramic products, giving lubricity and water retention, and improving the original strength of raw materials.The concentrated solution is adsorbed on the surface of ceramic particles, so that the friction between particles is reduced and the lubricity is enhanced, and the manufactured molded products have the required surface smoothness and dimensional stability; The sintered ceramic products with excellent electrical properties can be obtained

The capsule has high transparency and good color. Good formability and solidity after dipping in glue, which is more conducive to demoulding. The capsule shell has uniform thickness and good toughness. It does not contain chloroethanol, and the heavy metal indicators meet the requirements of the United States and European Pharmacopoeia

Hydroxypropyl Methyl Cellulose products have the maximum consumption in the area of suspension polymerization of vinyl chloride in China. In the suspension polymerization of vinyl chloride, the dispersed system has a direct impact on the product, PVC resin, and on the quality of its processing and products. Hydroxypropyl Methyl Cellulose helps to improve the thermal stability of resin and control the particle size distribution(in other words, adjust PVC density), and its amount accounts for 0.025% -0.03% of PVC production.

The hydroxypropyl methyl cellulose ether hpmc is the essential condition for thin bed technology for tile adhesive.Can be used as retarder, water retention agent, thickener and binder.Structural formula (n～2)/2 OR=-OH、-OCH3、-[OCH2CH(CH3)]nOH or-[OCH2CH(CH3)]OCH3 Specification of non modified products          Type      ItemHPMCPD/PDSHPMCPK/PKSHEMCEM/EMSEM40MNon surface treatmentPD100MPD150MPD200MPK40M PK100M PK150MPK200MEM60MEM70M EM100MEM150MEM200MEM6000SEM8000SEM10MSPD100MSEM20MSSurface treatmentPD150MS

HPMC (Hydroxypropyl methylcellulose) Capsules are two-piece capsules made from cellulosic raw materials that satisfy vegetarian, religion, cultural and policy needs.

Tile cement mortar is used to attach tiles on concrete or block walls. It comprises cement, sand, limestone,  HPMC and various additives, ready to be mixed with water before use.Normal tile cement is usually economic mortar which has lower content of cement and RDP (Redispersible polymer powder) than standard tile cement.

The hydroxypropyl methyl cellulose ether hpmc is the essential condition for thin bed technology for tile adhesive.Can be used as retarder, water retention agent, thickener and binder.For example, the performance of mortar is very different between natural sand and machine-made sand. Cellulose ether for ordinary dry mixed mortar shall have the following characteristics:Structural formula  (n～2)/2 OR=-OH、-OCH3、-[OCH2CH(CH3)]nOH or-[OCH2CH(CH3)]OCH3 Specification of non modified products          Type      ItemHPMCPD
