Ordinary methyl cellulose

Ordinary methyl cellulose

Methyl cellulose, also known as cellulose methyl ether, or MC (and abbreviation for MethylCellulose), is a long-chain substituted cellulose. At room temperature, Methyl cellulose exists as a white powder or fibrous material, characterized by its non-toxic, non-irritating, and non-allergenic properties. It swells in water, forming a semi-transparent, viscous colloidal solution, exhibiting neutrality to litmus. Methyl cellulose is insoluble in ethanol, ether, and chloroform but dissolves readily in glacial acetic acid. It's resistant to the effects of acids, alkalis, microorganisms, heat, and light, it remains unaffected by oils and greases. However, it combusts when reaching its ignition point. It's commonly used as thickeners; stabilizers; emulsifiers; excipients; dispersants; adhesives; film-forming agents; and hydrosol substitutes.

  • Methyl cellulose, also known as cellulose methyl ether, or MC (and abbreviation for MethylCellulose), is a long-chain substituted cellulose. At room temperature, Methyl cellulose exists as a white powder or fibrous material, characterized by its non-toxic, non-irritating, and non-allergenic properties.

Methyl cellulose is insoluble in ethanol, ether, and chloroform but dissolves readily in glacial acetic acid. It's resistant to the effects of acids, alkalis, microorganisms, heat, and light, it remains unaffected by oils and greases. However, it combusts when reaching its ignition point. It's commonly used as thickeners; stabilizers; emulsifiers; excipients; dispersants; adhesives; film-forming agents; and hydrosol substitutes. 

    Application 

    1. Methyl cellulose is widely used in the construction industry as an adhesive for cement, mortar, joints, and desliming. 

    2. It's used as film-forming agent and adhesive in cosmetics, pharmaceuticals and food industry. 

    3. It's also used as textile printing and dyeing sizing agent, synthetic resin dispersant, coating film-forming agent and thickening agent.

CMC for oil

CMC for oil

Petroleum grade CMC serves as a water-soluble colloid in the drilling mud system, composing the drilling fluid. It exhibits a high water loss control capability, functioning as a filtrate reducer. At lower dosages, it effectively controls water loss while maintaining the mud's other properties. The mud cake formed is of high quality, firm, and tough. Moreover, CMC demonstrates excellent temperature resistance and superior salt resistance. It retains its ability to reduce water loss and maintain a certain rheological behavior even at specific salt concentrations. In both brine and aqueous solutions, the viscosity remains almost unchanged. This makes it particularly suitable for the demands of offshore drilling and deep wells.
