Hydroxypropyl methyl cellulose (HPMC) is a non-ionic cellulose ether polymer based on cellulose, a natural polymer derived from refine cotton linter,which are offered as free flowing powder.
According to the degree of substitution and modification of substituent, they have different chemical properties and benefits after alkalization and etherification reactions with Sodium hydroxide,Cholromethane,and propylene epoxide.
SLEOCHEM’s HPMC products are widely used in various construction fields, such as tile adhesives, grouts, EIFS, masonry mortars, repair mortars, cement render plaster, skim coat/wall putty, gypsum-based materials, detergents, etc.
