HPMC VS HEC: 6 Differences You Need to Know!
HPMC and HEC, both of them are a kind of cellulose ether. but what is the difference between them? HPMC VS HEC. In recent years, the output and consumption of HPMC have been increasing rapidly. HPMC is an ironic cellulose ether. it begins refined cotton after alkalization treatment. Propylene oxide and methyl chloride is the etherifying agent in the HPMC manufacturing process. After a series of reactions, get HPMC. But HEC also begins refined cotton after alkalization treatment. With acetone, HEC uses ethylene oxide as the etherifying agent. So HEC has more hydrophilic than HPMC. It is prone to absorb moisture.
