HPMC is hydroxypropyl methylcellulose is water-soluble, non-ionic polymer that is commonly used as a thickener and water retention agent in a variety of applications- tile adhesives, wall putty, EIFS- the compound forms colloids when dissolved in� water. This non-toxic ingredient is combustible and can react vigorously with oxidizing agents.
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.

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.
