Methyl Cellulose (Mc)

Methyl cellulose (mc) 1. Specifications: Methoxyl: 28. 0% -32. 0% ; Moisture: 5% max; Viscosity (2% , 20 c) mpa. S: 5-100000 (see viscosity specifications) ; Ash: 1% max; Gelling temperature: 52-67 c2. Property: Mc is a kind of non-ion aqueous cellulous ether, white or white-similar powder or granule, no odor or taste, nontoxic, with a little hygroscopicity. Different substitution offers different solubility, usually medium substitution (ds between 1. 5-2. 0) comes under cool aqueous model, and finds widest applications. It dissolves in cool water and some organic solvents, does not dissolve in hot water. In hot water at 80-90 c it dissolves and swells, after cooled down, dissolving quickly. Its solution possesses reversible hot gelling characteristic, stable to acid and alkali, is not affected between ph 2-12, with excellent anti-mildew ability, capable of dispersing, emulsifying, agglomerating, thickening, holding water, forming film etc. Film formed by its offers superior toughness flexibility, transparency and oil resistance.
