Product Name:Methyl Cellulose
English Name:Methyl Cellulose
CAS No.:9004-67-5
Aliases:Cellulose Methyl Ether, E461
Molecular Formula:(C6H10O5)n
Physical Properties:Methyl cellulose is a non-ionic cellulose ether prepared by introducing methyl groups into cellulose via etherification. It exhibits thickening, surface activity, film-forming ability and thermal gelation properties. Its solutions are stable over a pH range of 3.0–11.0. It forms a gel upon heating and melts upon cooling, with a gelation temperature range of 50–70°C. It dissolves in cold water to form clear viscous solutions, is insoluble in hot water, and can form films upon water evaporation.
Uses:Mainly used as a thickener, emulsifier, dispersant and stabilizer. It serves as a dispersant in suspension polymerization of vinyl chloride and styrene, preventing solvent evaporation. It is also widely applied in construction, coatings, food and pharmaceutical industries.
Technical Specifications:
Degree of substitution (DS) is 2.4–2.7.
Gelation temperature range is 50–70°C.
Stable in solutions with pH 3.0–11.0.
Exhibits thermal gelation: gels upon heating and melts upon cooling.
Packaging: 25 kg/bag.
