China HPMC Construction Grade Powder HPMC 200000 cps
China HPMC Construction Grade Powder HPMC 200000 cps
HPMC(Hydroxypropyl methylcellulose), also known as hypromellose, cellulose hydroxypropyl methyl ether, is obtained by using high purity cotton cellulose as a raw material and special etherification under alkaline conditions.
Cellulose ether HMPC for render is white powder or granule made from highly pure cotton - cellulose by reaction of etherification under alkal. HPMC is characterized by water solubility, water retention, nonionic, stability of the PH value, surface activity, temperature reversible gelling properties, thickening property, film formability, lubrication property etc.,without any organs of animals, fat and other bioactive constituents.
