Production Process
Hydroxypropyl methylcellulose (HPMC) is made of refined cotton after being pulverized, then reacted with sodium hydroxide (liquid caustic soda) solution for alkalization, and then added
chloromethane + propylene oxide for etherification reaction to form crude HPMC After neutralization (PH value adjustment), pressure filtration, drying, crushing and sieving, a certain fineness of
pure HPMC can be obtained. The finished product has a slight odor, the smell of methane.
