Cellulose ethers – HPMC


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:

Chemical Structure of Joincel cellulose

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.
