HYDOXYPROPYLMETHYLCELLULOSE JOINCEL
Trade Name: Joincel
Chemical name: Hydoxypropylmethylcellulose (HPMC)
CAS No.: 9004-65-3
Abbreviation: HPMC
Chemical Structure of Joincel cellulose ethers is composed of linear chains of etherified cellulose with different molecular weight. The chains have certain degree of substitution by Methoxy-groups and Hyroxypropyloxy-groups:
Joincel Nonionic cellulose ethers are used as water-retaining additives, thickeners, binder and filler stabilizers in water solutions, as dispersants, emulsifiers and plasticizers in construction industry, dry mix industry, production of waterborne paints and lacquers; as well as in ceramics production and polyvinylchloride polymerization, in household cleaners and pharmaceutical medicines.
