Detail

HPMC-Hydroxy propyl methyl cellulose   

HPMC is made by propylene oxide, methyl choride with alkali-cellulose after a chemical process   called etherification under rigidly controlled conditions. The resultant nonionic polymer is purified , dried and ground to a fine white powder, this water-insoluble cellulolse is turned into water-soluble nonionic polymer.

HPMC is a good film-former and varies somewhat in physical and chemical properties.   HPMC is quite hydrophilic and readily soluble in cold water.


Main application


1. Construction industry: with good thixotropy and adhesive, so that mortar can be pumped. As binders in plaster, gypsum material, putty powder or other materials, it has the function of thixotropy and coagulation, which can improve and extend the operational time of painting. As the adhesion enhancer for bonding tiles, marble, plastic decoration, it can reduce the dosage of cement. With water retention, it makes the slurry not dry too fast and cracked, increasing the strength after hardening.


2. Ceramic industry: widely used as a binder in the manufacture of ceramic products.


3. Paint industry: as a thickening agent, dispersing agent and stabilizer in the paint industry, and have a good compatibility in water or organic solvents, also can be used in paint remover.


4. HPMC for detergent:   HPMC for daily chemical aqueous solution has the surface activity, make its have emulsification, protective colloid and relative stability.
