Hydroxypropyl methylcellulose(HPMC) is a type of nonionic cellulose ether made from natural high molecular materials through a series of chemical processes. With almost all properties of methyl cellulose (MC), it is the auxiliary agent of first choice in the production of top-quality construction materials. With such favorable features as high water retention, good dispersancy, high degree of fineness, nice placeability and convenience to dissolve, it is applicable to the production of innovative construction materials like dry-powder mortar, waterproof putty powder (paste) for indoor and outdoor walls, binding agent, gap filler, interface finishing agent, water paint, self-leveling agent, etc. In the production of construction materials, cellulose ether is an indispensable additive

Physical and Chemical Properties
