What is HPMC?

HPMC Manufacturers in China A Growing Industry

HPMC is a modified cellulose ether that is prized for its excellent film-forming, thickening, and stabilizing abilities. It is made by chemically modifying cellulose through the introduction of hydroxypropyl and methyl groups. The degree of substitution of these groups can be tailored during the manufacturing process, resulting in HPMC with specific solubility and viscosity characteristics. This customizability allows users to select the most appropriate type of HPMC for their needs.

HPMC is synthesized through the etherification of cellulose with propylene oxide and methyl chloroacetate. This process results in a polymer that contains hydroxypropyl and methoxy groups. The degree of substitution, which indicates the number of hydroxyl groups replaced by methoxy and hydroxypropyl groups, significantly influences HPMC's properties. Generally, HPMC with higher hydroxypropyl content is more soluble in water.
