Hydroxyethyl cellulose HEC
Specification: Molecular formula: [C6H7O2 (OCH2CH2OH) x (OH) 3-x] n
Description: tasteless, odorless, non-toxic white or light yellow powder particles flow easily; non-ionic water-soluble polymer
Product properties: a thickening, binding, emulsification, dispersion, stability, and to maintain moisture to form a film and provide protective colloid effect, soluble in cold water and hot water, can provide a wider range of solution viscosity; is a high concentration of electrolyte solution thickener; water capacity than twice as methyl cellulose, has a good flow of regulatory.
Characteristics of use: 1, Polymerization 2, latex paint, polymer 3, oil drilling 4, 5, daily
