Hydroxy Ethyl Methyl Cellulose Cellulose are The Water Soluble Non-Ionic Cellulose Ethers Available In A Wide Range Of Viscosities And Thermal Gelation Temperatures.

Hydroxypropyl Methyl Cellulose (HPMC) is non-ionic cellulose ether made from natural high polymer cellulose by series of chemical processing. It is odorless, tasteless and non-toxic white powder, which could be dissolved in cold water to form transparent and thick solution. It possess thickening, binding, dispersing, emulsifing, film forming, suspending, absorbing, gelling, surface activity, water maintaining and protective colloid properties. Hydroxypropyl Methyl cellulose has a wide usage. The products from our company are mainly used in building material, coating industry, ceramics, agriculture, daily chemical and other industries.

APPLICATION PERFORMANCE: (1)Water Solubility Soluble water in any proportion,the highest density depends on viscosity,and solution does not be effected by PH value.
(2) Solubility in Organic solvent HPMC can dissolve in some organic solvents or organic aqueous solutions such as ethylidene chloride,alcohol ones.
(3) Heat Gelling When their aqueous solutions are heated to a certain temperature, reversible reaction may occur,but its fast gelling can be controlled.
(4)Non-ion Electric Charge HPMC is non-ion cellulose ether,does not complex with metal ions or result in insoluble precipitations. (5) Thickening Its water solution provides thickening effect whoich has to do with viscosity,density and system.
(6) Water-holding HPMC or its solution can absorb and hold moisture.
(7) Film-forming HPMC can be made into smooth,tough and elastic film which offers excellent oil resistance and antioxidancy.

Used as cement grinding aid, to improve grinding efficiency, reduce energy consumption without compromising the performance of the cement. Used as curing additives in cement admixtures.

VAE Redispersible powder is a white free-flowing Vinyl Acetate-Ethylene copolymer base powder, readily redispersible in water to form stable emulsion. It combines the original characteristics of EVA emulsion with the special property of free flowing powder, and it is easy and convenient to handle and storage. Dry mixing with other powder materials such as cement, sand and aggregate at the factory can ensure consistent and reliable performance at the work site. VAE is used in combination of cement and plaster, or as a sole binder in other dry-mix formulation. VAE improves adhesion, flexural strength, abrasion resistance and workability in a variety of product sold in dry powder form, including thin-set mortars, tile adhesives, grout, finishing plasters and troweling compounds. VAE is a general purpose copolymer powder that can be used in the building materials and adhesives field as a binder component. In the general formulation the amount of VAE is about 5 to 20% based on the weight of cement.

Applications: Tile adhesives, Repair mortars, Self leveling compounds, Mineral plasters, Gypsum based compounds.
