Cellulose ether series

Technical grade Methyl Cellulose (MC), Hydroxypropyl Methyl Celluloes (HPMC)

Product properties and applications
These products are a water-soluble ether, with thermal gelation properties, which has excellent cold-water soluble and hot water insoluble properties, It is a non-ionic cellulose ether mixture, the solution of non-ionic charges, which can’t react with metal salts or ionic compounds. It has PH stability, strong enzyme resistance and metabolic inertia; also has a good dispersion, emulsification, thickening, adhesion, water retention and protective colloid properties, so they are which is widely used in construction, paint, synthetic resin , ceramics, tobacco, textile, daily chemical, petrochemical and electronics industries.
