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.
Hydroxypropyl Methyl Cellulose (HPMC) are widely used in construction, pharmaceutical,food, cosmetic,detergent,paints,as thickener, emulsifier, film-former, binder, dispersing agent, protective colloids.We can provide the regular grade HPMC, we also can provide modified HPMC according to customer re
Hydroxypropyl methyl cellulose (HPMC) is a natural polymer materials as raw materials,through a series of chemical processing and prepared non-ionic cellulose. It contains almost methyl cellulose(MC) of all the performance, your first choice for production of high quality building materials additive
