Hydroxypropyl Methyl Cellulose (CAS 9004-65-3)
Product Overview
Hydroxypropyl Methyl Cellulose (HPMC) is a non-ionic, water-soluble cellulose ether derived from natural polymer structures through a series of chemical modifications. Exhibiting excellent properties such as reversible thermal gelation, water retention, film-forming capacity, and surface activity, this compound functions as a versatile rheology modifier, stabilizer, and water-binding agent across multiple formulation-driven industries.
Technical Specifications
