Methyl Hydroxyethyl Cellulose Ether (MHEC)
Overview：
Methyl hydroxyethyl cellulose ether(MHEC) is a kind of methyl cellulose derivative which is made from natural high polymer cellulose. It is widely used in many different industries as water retention agent, thickener, adhesive agent and dispersant etc. It could dissolve in water and form a clear solution with specific viscosity. MHEC have a good stability even though in alkaline environment and provide a good stability in heat environment. Widely used in drymix mortar industry, oil drilling, detergent and paint ＆ costings etc.
The most important properties of cellulose ether polymers include:
Good thickening / thickening efficiency
Available in a wide range of molecular weight and viscosity
Excellent properties as a water-retaining agent
Excellent resistance to dissolved inorganic salts
Excellent solution clarity
Low toxicity and environmental protection

Methyl 2-Hydroxyethyl Cellulose is a odorless, tasteless and non-toxic white powder, which can be dissolved in cold water to form a transparent viscous solution. It has the characteristics of thickening, bonding, dispersion, emulsification, film-forming, suspension, adsorption, gelation, surface activity, water retention and colloid protection. Because aqueous solution has surface active function, it can be used as colloidal protective agent, emulsifier and dispersant. Hydroxyethyl methylcellulose aqueous solution has good hydrophilicity and is a high-efficiency water retaining agent. Hydroxyethyl methyl cellulose contains hydroxyethyl group, so it has good mildew resistance, good viscosity stability and mildew resistance during long-term storage.
