Product Description

Introduction
HPMC use highly pure cotton as raw material. It is a kind of white or whitish powder. 
HPMC decreases with the decrease of methoxide content, increase of gel point, decrease of water solubility and decrease of surface activity. 
HPMC has thickening ability, salt resistance, low ash powder, pH stability, water retention, dimensional stability, excellent film forming, and a wide range of enzyme resistance, dispersion and adhesion.
It's white or off-white powder, non-toxic tasteless, and readily soluble in hot or cold water. HPMC also used for ceramics, tobaccos and detergents, etc.

Function of HPMC
1. Construction industry: As a water retaining agent and retarder for cement mortar, the mortar has pumpability. In the plaster, gypsum, putty powder or other building materials as a binder, improve the spreadability and extend the operation time. Used as a paste tile, marble, plastic decoration, paste enhancer, can also reduce the amount of cement. The water retention of HPMC enables the slurry to not crack too quickly after application and enhance the strength after hardening.
2. Ceramic manufacturing: widely used as a binder in the manufacture of ceramic products.
3. Coating industry: as a thickener, dispersant and stabilizer in the coating industry, it has good compatibility in water or organic solvent. As a paint stripper.
4. Ink printing: As a thickener, dispersant and stabilizer in the ink industry, it has good compatibility in water or organic solvent.
5. Plastic: used as a mold release agent, softener, lubricant, etc.
