Hydroxypropyl Methyl Cellulose
hydroxypropyl methyl cellulose introduction
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.

hydroxypropyl methyl cellulose application
Joint cement: added to joint cement for gypsum board to improve fluidity and water retention.
Latex Putty: Improves the flow and water retention of resin latex-based putties.
Stucco: As a paste in place of natural products, it can improve water retention and improve adhesion to the substrate.
Coatings: As a plasticizer for latex coatings, it can improve the performance and fluidity of coatings and putty powders.
