- Furthermore, HPMC contributes to the overall sustainability of building materials. Since it is derived from renewable sources (wood pulp), its production has a lower environmental impact compared to synthetic alternatives. Additionally, its biodegradable nature means that it does not persist in the environment after disposal, making it an eco-friendly choice for green building projects.
4. How to determine the quality of hydroxypropyl methyl cellulose (HPMC) simply and intuitively?
Application
Die Größe des Makromoleküls wird üblicherweise durch dessen Viskosität in 2-prozentiger wässriger Lösung charakterisiert; handelsüblich sind die HPMC-Typen 4M (für ca. 4.000 mPa·s), 15M (für ca. 15.000 mPa·s) und 100M (für ca. 100.000 mPa·s).[11]




different grades of hpmc.
HPMC
Hydroxypropyl methylcellulose (HPMC) is a synthetic, water-soluble polymer that is used in a variety of applications. It is a type of cellulose ether, which means that it is derived from cellulose, the main structural component of plant cell walls. HPMC is commonly used as a thickening agent, stabilizer, and emulsifier in a range of products, including pharmaceuticals, food and beverages, personal care products, and construction materials.
