Overview

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.

Features

Excellent wettability\dispersibility, adhesion, thickening, emulsifying, water retention and film-forming, as well as impermeability to grease; The resulting film has excellent toughness, flexibility and transparency; Compatible with other emulsifiers; Easy to salt out

Application

Functions in oil, natural gas drilling, well digging and other projects: as a drilling mud washing fluid treatment agent, it can resist the pollution of various soluble salts.;In the textile, printing and dyeing industry, methylcellulose is used as a sizing agent for light yarn sizing of cotton, silk wool, chemical fibers, blended and other strong materials.;In the paper industry, methyl cellulose is used as a paper surface smoothing agent and sizing agent.;Used in the ceramic industry, it can be used as an adhesive for blanks, plasticizers, suspending agents for glazes, and color-fixing agents.;Used in construction, the function is to improve water retention and strength.;In the food industry, thickeners, stabilizers, binders or excipients can be used.
