Methyl Hydroxy Ethyl Cellulose
CheSiloTM Methyl Hydroxy Ethyl Cellulose
CAS Number: 9032-42-2
Molecular Formula: [C6H7O2（OH）x-m-n（OCH3）m（OCH2CH（OH）CH3）n]x
Structural formula:
Wherein, R stands for –H, -CH3 or –CH2CHOHCH3 and n for degree of polymerization
CheSilo Methyl Hydroxy Ethyl Cellulose(abbr.CheSilo MEC) is a non-ionic,dissolving in cold or hot water. It is widely used as thickener, protective colloid, stabilizer, suspending aids and water-retention agents in many industrial applications.

Note:
1.CheSilo MEC consists of pure grades and modified grades providing special properties for detailed application.
2.The viscosity is based on Brookfield RV,20rpm at 20℃ in 2% aqueous solution.
3. MEC 300(S) means two grades: MEC 300 or MEC 300S(same viscosity with delayed solubility)
