HPMC E-5 / E-15
HPMC E-5 / E-15 – Premium Quality Hydroxypropyl Methylcellulose for Pharmaceutical and Industrial Use
Hydroxypropyl Methylcellulose (HPMC) grades E-5 and E-15 are high-grade cellulose ethers widely used as thickening agents, film formers, and controlled-release excipients in pharmaceuticals, construction, and food industries. Imported HPMC ensures consistent quality, excellent solubility, and reliable performance in various formulations.
HPMC is favored for its non-toxic, biodegradable nature and its ability to form clear, stable gels and films, making it indispensable in tablet coatings, adhesives, and cosmetic products.
