Product Description Product DescriptionHydroxy Ethyl CelluloseCAS No.:9004-62-0Hydroxy Ethy Cellulose (HEC for short) is a non-ionic soluble cellulose ether, both soluble in cold and hot water, with thickening, suspension, adhesion, emulsification, film-formation, water retention, protective colloids and other properties, widely used in coatings, cosmetics, oil drilling and other industries.AppearanceHEC is a white to light yellowish, oderless and tastless powder, readily soluble in hot or cold water to form a viscous gel solution. When pH in solution is within 2 to 12, the solution is quite stable. CharacteristicSince HEC group is nonionic one in water solution, it won't be reacted with other anions or cations and insensitive to the salts. But HEC molecule is capable of generating esterification and etherification , so it is possible to make it insoluble in water or improve its properties. HEC also has good film-forming ability and surface activity.SpecificationHydroxyethy CelluloseTest itemsTesting standardsAppearancewhite to light cream, free-flowing powderMolar substitution degree(MS)≥2.3Brookfield RV 2%250-180000 mPa.sLoss on drying≤5%Residue on ignition≤5%Ash content≤5%light ratio (2% Solution)≥85%PH ( 1% aqueous solution, 25oC )6.0-8.0Particle Sizemin. 98% pass through 100 meshApplicationApplication FieldsApplication RangeFunctionOil-drillingOil drillingViscosifier and water loss controllerPaintingLatex paint, polymer emulsifyingThickeningConstructionCement, mortarThickening, water-retaining, retardingCosmeticsToothpaste, shampoo, CreamThickening, stabilizingCeramicsEnamelingWater-retainingPaper-makingSizingThickening, water- retainingPharmaceuticalLotion, OintmentThickeningPackingN.W.: 25±0.25kg / package, 16 ton/ 20'FCL with pallets, 18MTS/20'FCL without pallets.Inner: Polyethylene plastic film bag, Outer: Three-in-one composite paper bag.
