HEC with our performance in oilfield is our specially produced non-ionic soluble cellulose ethers derived from natural fibers.HEC has excellent functionalities in thickening, suspension, binding, emulsion, film stability, dispersion, water retention, anti-microbial properties and colloid protection, etc.It can be widely used in paints, cosmetics, oil drilling and other industries.
HEC provides high performance in increasing viscosity,and is excellent in control filtration loss in oilfield drilling and completion fluids.HEC is stable to various salts,even at Calcium salt solution.Oilfield fluids containing HEC exhibit high apparent viscosity,high yield point and low fragile gel strength.Its shear-thinning behavior known as pseudoplasticity help both increase penetration rates under high shear and provide excellent suspending action for optimum hole cleaning under low shear while viscosity is regained.
HPMC is odorless, tasteless,non-toxic cellulose ethers produce from natural high molecular cellulose through series of chemical processing and achieved.It is white powder with good water solubility. It has thickening, adhesion ,dispersing, emulsifying, film, suspended, adsorption, gel,and protectiv
