Sodium Carboxyl Methyl Cellulose ( CMC )
CMC for food CMC for Toothpaste CMC for Oil Drilling Liquids CMC for Detergent
CMC for Building CMC for Ceramic CMC for Paper CMC for textile
Redispersible polymer powder produced by spray-drying special water-based emulsion, mostly based on vinyl acetate-ethylene (VAE), and then obtained a free flowing organic polymer powder. It can re-disperse in water, and form a film after water evaporation by coalescence of individual polymer particles. The film acts as an organic binder, to glue together different substrates, reinforce mortar structure and provide excellent adhesion at cement or gypsum based dry mixed mortar substrate interface.

Hydroxypropyl methylcellulose( HPMC)
Advantages:
1. Water soluble and thickening ability: this product is soluble in cold water, and it can form transparent sticky solution. In organic solvent of dissolved: because it contains a certain amount of hydrophobic methyl, this product is soluble in some organic solvent; it is also soluble in water and organic mixed solvent.
2. Hydroxypropyl methyl cellulose (HPMC) salt resistance: because ion and the polyelectrolytein exists in this product, its metal salt or organic electrolyte aqueous solution is stable.
3. Surface activity: HPMC for daily chemical aqueous solution has the surface activity, ensuring its emulsification, protective colloid and relative stability.
4. Low ash content: because ion exist in this product, in preparation process we can use hot water washing for effective refinement, so its ash content is very low.
5. pH stability: HPMC aqueous solution viscosity in the range of pH3.0-11.0 is more stable.
6. Water retention effect: this product is hydrophilic and its solution has high viscosity.
7. Film-forming property: HPMC can generate strong pliable and transparent sheet, which has the good oil resistance to ester performance.
