Qingquan Cellulose specializes in the manufacturer direct sales of high-quality Hydroxypropyl Methyl Cellulose (HPMC), a versatile cellulose ether essential for the construction and coatings industry. This multifunctional additive acts as an efficient putty thickening powder, a stable coating emulsifier, and a reliable cement thickener, significantly improving the workability, consistency, and final performance of various building materials.
Coating emulsifier hydroxypropyl methyl cellulose is a key product of QINGQUAN company, characterized by high purity, high quality, and low price. We have been specializing in Putty thickening powder hydroxypropyl methyl cellulose production for over 15 years.
Manufacturer Direct Sales of Putty Thickening Powder Coating Emulsifier Cement Thickener Hydroxypropyl Methyl Cellulose
As a nonionic cellulose mixed ether with excellent performance, HPMC has good dispersing, emulsifying, thickening, bonding, water retention and glue retention properties as other cellulose ethers (such as CMC, MC, HEC, MHEC, HEMC, HBMC). It is soluble in water, also soluble in ethanol and acetone below 70%. It can be widely used as thickener and adhesive.HPMC has thickening, dispersing and emulsifying film-forming properties, and is widely used in petrochemicals, building materials, ceramics, textiles, daily-use chemicals, synthetic resins, coatings and electronics and other industrial fields.
Chemical formula of the product
HPMC is a partially methyl and partially polyhydroxypropyl ether of cellulose, which is obtained by alkalizing cellulose and then reacting it with two etheric agents, chloromethane and propylene oxide .
