1. Hydroxypropyl Methyl Cellulose(HPMC) is a non-ionic cellulose ether made from natural polymer cellulose and made up through a series chemical processing. They are the white powder of odorless, tasteless and non-toxic, it can be swelled into clear or slightly muddy colloid solution in cold water. They have properties like thickening, bonding, dispersing, emulsifying, film, suspension, adsorption, gel, surface activity, maintaining water and protective colloid and so on.

CAS No.: 9004-65-3
Packaging:25kgs craft paper bags
Appearance:white powder
Source: Wood Pulp and Cotton Linters
Function: Thickening,dispersing, emulsifying, film forming and tableting excipients.
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. Ink printing,Plastic, PVC, Textile and others.
