  • Ashland Hydroxyethyl Cellulose A Versatile Polymer for Various Applications


  • Hydroxypropyl Methyl Cellulose (HPMC) is a versatile and essential cellulose ether that is widely used across various industries ranging from pharmaceuticals to food, construction, and personal care products. As a non-ionic compound derived from natural cellulose, HPMC offers excellent properties such as water retention, film-forming ability, and thermal stability. With the increasing demand for HPMC, many suppliers in China are stepping up to meet the needs of both domestic and international markets.


  • One of the key characteristics of HPMC is its ability to act as a thickening agent, stabilizer, and emulsifier. It is commonly used in pharmaceuticals as a controlled-release agent, binder, and film-forming agent in tablets and capsules. In the construction industry, HPMC is used as a thickener in mortar, plaster, and grout to improve workability and adhesion. It is also used in paints, coatings, and adhesives to enhance their performance and durability.
