As HPMC manufacturer, our HPMC production process is as follows:
Hydroxypropyl methyl cellulose (HPMC) is made from refined cotton after being pulverized, and then alkalized with sodium hydroxide (liquid caustic soda) solution, and then monochloromethane + propylene oxide is added for etherification to form crude HPMC , After neutralization (pH adjustment), filter press, drying, crushing and sieving, a pure HPMC product of certain fineness is obtained. The finished product has a slight smell, the smell of methane.
