Hydroxypropyl Methyl Cellulose
(HPMC)
Hydroxypropyl methylcellulose (HPMC) belongs to the group of cellulose ethers in which hydroxyl groups have been substituted with one or more of the three hydroxyl groups present in the cellulose ring. HPMC is hydrophilic (water soluble), a biodegradable, and biocompatible polymer having a wide range of applications in drug delivery, dyes and paints, cosmetics, adhesives, coatings, agriculture, and textiles. HPMC is also soluble in polar organic solvents, making it possible to use both aqueous and nonaqueous solvents. It has unique solubility properties with solubility in both hot and cold organic solvents. HPMC possesses increased organo-solubility and thermo-plasticity compared to other methyl cellulose counterparts. It forms gel upon heating with gelation temperature of 75–90oC.

Use in Construction Materials
HPMC is used primarily in construction materials like tile adhesives and renders[6] where it is used as a rheology modifier and water retention agent.
Gomez Chemical Hydroxypropyl Methyl Cellulose（HPMC）or Hypromellose is a water-soluble, non-ionic cellulose ether polymer. Depending on the degree of substitution and modification, the chemical properties can be different. With excellent properties such as thickening, adhesion, dispersion, suspension, surface activity, and water retention, our HPMC products are widely used in various fields, such as tile adhesives, grouts, masonry mortars, repair mortars, waterproofing mortars, flooring compounds, skim coat/wall putty, gypsum-based materials, etc.
According to different application requirements, our technical engineers have developed and customized various grades and categories of HPMC products to meet the specific needs of customers from different industries. Our technicians are available to answer any questions you have at any time and provide you with tailor-made formulations and customized service.

Cellulose HPMC Features
Thickening Effect
HPMC shows excellent stickiness to wet mortar. That can significantly increase the adhesion of wet mortar to the base layer and improve the sag resistance of the mortar
Water Rentention
HPMC has a stable water retention capacity in a wide temperature range, although changes in ambient temperature will affect its water retention capacity.
Anti-sagging Ability
when the mortar is constructed with a considerable thickness; for the tile pasting project, it means that the tiles pasted to the wall will not be displaced due to gravity.
