Introduction to Thickening Agent Mecellose Hydroxypropyl Methyl Cellulose HPMC

Hydroxypropyl Methylcellulose (HPMC), na ang Chinese na pangalan ay hydroxypropyl methylcellulose, ay isang semi-synthetic, non-ionic cellulose eter na nakuha sa pamamagitan ng chemically modifying natural cellulose. Ang puting pulbos na ito ay maaaring bumuo ng isang transparent na malapot na solusyon pagkatapos matunaw sa tubig. Ito ay may mahusay na pampalapot, pagpapanatili ng tubig, katatagan at mga katangian ng pagbuo ng pelikula. Ito ay isang kailangang-kailangan na multifunctional additive sa maraming larangan tulad ng konstruksiyon.
