KimaCell®MC A30M Methylcellulose is white powder or fiber, non-toxic, tasteless. Methylcellulose is a product obtained by methylating all or part of the three hydroxyl groups in glucose that constitutes cellulose. 6%. If all methylation, the degree of substitution is 3, the content of methoxy is 45.6%. The general product contains 26% to 33% methoxy, and its degree of substitution is 1.7 to 2.2. Products with a degree of substitution of 1.3 to 2.6 are soluble in water, pyridine, and glacial acetic acid, and products with a degree of substitution of 2.4 to 2.8 are soluble in polar solvents. The properties of the product are related to the degree of substitution. When the degree of substitution is the same, the product with more uniform distribution of substituents generally has a lower degree of polymerization and better solubility. When heated, its viscosity initially decreases with increasing temperature, but becomes viscous and gels sharply after reaching a certain temperature. Its powder and air can form explosive mixtures. In case of fire, high heat can cause combustion and explosion.

KimaCell® MC A30M Methyl cellulose is Widely used in construction industry. Such as cement, mortar, joint mortar and other mixtures. It is used as a binder for film-forming agents in cosmetics, medicine, and food industries, and also as a sizing agent for franc textile printing and dyeing, a dispersant for synthetic resins, a film-forming agent for paint, and a thickener. Methyl cellulose is a very stable substance that can withstand the effects of acids, alkalis, microorganisms, heat, etc. In the human body, it is completely unchanged and excreted out of the body. The aqueous solution is stable at neutral and normal temperature, and gelation and precipitation occur at high temperature. The gelling temperature depends on the viscosity and concentration of the solution, and the gelling temperature is lower when the viscosity and concentration are large. In the presence of inorganic salts, the viscosity can be increased. Because it is a non-ionic solution, polyvalent metals cannot precipitate it, and only when the concentration of electrolytes and other dissolved substances exceeds a certain limit, gelation will occur. The aqueous solution has surface activity, forms a thin film after drying, undergoes a reversible transformation from sol to gel in sequence upon heating and cooling.
