Mô tả thêm:
HPMC (hydroxypropyl methylcellulose) is a non-ionic cellulose ether derived from natural cellulose through chemical modification, valued as a water-soluble polymer that thickens, binds, forms films, stabilizes and retains water. It holds moisture over time, increases solution viscosity, forms flexible transparent films, gels when heated and returns to liquid on cooling, and remains chemically stable and compatible with many other ingredients. In construction, it improves workability, water retention, adhesion and crack resistance in products such as tile adhesives, dry-mix mortar, wall putty and self-leveling compounds; further applications extend into the pharmaceutical industry.
