mhec chemical-Methyl Hydroxyethyl Cellulose (MHEC)
Methyl Hydroxyethyl Cellulose is a white, yellow-white or off-white powder or granules, hygroscopic after drying. It is a methylcellulose based cellulose. It has several properties used in the pharmaceutical and construction industries. Methyl Hydroxyethyl Cellulose (MHEC) alone or in combination is the most widely used cellulose in mortar formulations. MHEC has various properties such as thickening, emulsifying, binding, forming, protective colloid and water retention.
Due to its high degree of methoxylation, MHEC is the only cellulose derivative with the best water retention, which is the only reason why MHEC is sold for use in cement-based wall putties and mortars. MHEC is also used in cement-based tile adhesives and grouts.
Properties of Methyl Hydroxyethyl Cellulose
● 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
Applications of Methyl Hydroxyethyl Cellulose
Methyl hydroxyethyl cellulose (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 has 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.
