Methyl cellulose properties vary with the degree of etherification and medium.
Methyl cellulose is an off-white powder or fibrous odorless substance. It is tough, non-toxic, odorless and can be made into food packaging adhesive. Low concentration of methyl cellulose solution has high viscosity, suitable for water-soluble adhesive anvil viscosity builder, etherification degree 1.6-2 products can be dissolved in cold water, can be bonded to leather, wallpaper, can be used as a phenolic resin viscosity regulator, stabilizer of polyvinyl acetate.
Methyl cellulose (MC) is almost insoluble in anhydrous ethanol, ether and acetone. It is rapidly dispersed and dissolved in hot water at 80-90℃, and rapidly dissolved after cooling down, the aqueous solution is quite stable at room temperature, and it can gel at high temperature, and this gel can be transformed with the temperature and solution each other. It has excellent wettability, dispersion, adhesion, thickening, emulsification, water retention and film-forming properties, as well as impermeability to grease. The formed film has excellent toughness, flexibility and transparency, because it is non-ionic, it can be paired with other emulsifiers, but it is easy to salt precipitation, and the solution is stable in the range of PH 2-12.
