| Description |
Methylcellulose is a nonionic cellulose ether made by introducing methyl groups into cellulose by etherification. Methylcellulose has 4 important functions: thickening, surface activity, film-forming, and thermogel formation (melting when cooled). Methylcellulose has a unique thermal gelation property, that is, it forms a gel when heated and melts when cooled, and the gelling temperature ranges from 50 to 70 °C. Methylcellulose is widely used in the construction industry, such as as a binder for cement, mortar, joint desliming, etc. It is used as a film former and adhesive in the cosmetic, pharmaceutical and food industries. Also used as textile printing and dyeing sizing agent, synthetic resin dispersant, coating film former and thickener. |
