Cellulose ethers are divided into hydroxypropyl methyl cellulose (HPMC) and hydroxyethyl cellulose (HEC). They are both cellulose ethers, but have some differences in physicochemical properties and applications.
Hydroxypropyl Methyl Cellulose (HPMC) is a non-ionic cellulose ether made from refined cotton, a natural polymer material, through a series of chemical processes.
It is an odorless, tasteless and non-toxic white powder, soluble in cold water to form a transparent viscous solution with multiple.
Hydroxyethyl Cellulose (HEC) is a non-ionic soluble cellulose ether with excellent water retention, thickening, suspension properties, etc.
Thanks to its unique physicochemical properties, HEC is widely applied in many industrial fields.
Cellulose Ether Series product is widely used in various industries including building materials, painting and coatings, synthetic resins, ceramics, medicine, food, textile, agriculture, cosmetics and tobacco, etc.
