Oil Drill Grade Hydroxyethyl Cellulose

Oil drilling HEC
Used as thickening agent to make mud achieve good mobility.

Product Details

Hydroxyethyl Cellulose thickening agent can be used as oil well workover fluid and cementing agent. Help to provide clarification of the low fixed content solution, thus greatly reducing the structural damage to the wells. 

Hydroxyethyl Cellulose configuration using drilling fluid, based on its low solids content, can effectively increase drilling stability. These properties inhibition of liquid can be used to inhibit the fluid medium to high hardness of the rock and heavy shale or shale drilling.

Reinforcement in the cement operations, Hydroxyethyl Cellulose slurry can reduce the hydraulic friction, the loss of rock to minimize water loss.

Thylocell® Hydroxyethyl cellulose is a kind of water soluble nonionic cellulose ether from natural cellulose through chemical modification.It is tasteless,odorless,non-toxic and white or yellowish solids in powder form.Thylocell HEC is nonionic cellulose ether.It is easily dissolved in cold and hot water,resulting in solution with a wide range of viscosity.It has many functions,including thickening,binging,emulsifying,dispersing,water-maintaining and colliod stabilizing and protecting.

♦ Significant thickening effect

♦ Excellent color display

♦ Film forming and storage range of PH value

♦ Good compatibility with other material (pigments, auxiliaries, fillers and salts)

♦ High rheological properties

♦ Good workability and leveling performance


Excellent Advantage

♦ High thickening efficiency. Due to there are many different kind of thickening agents, any requirement for thickening efficiency can be reached, especially for aqueous thickening.

♦ Good compatibility. High degree and serialization of compatibility of the modern countless components in the latex paint formulations. Compared to non-cellulosic thickeners, using cellulosic thickeners in the formulation could provide a wider choice.

♦ Good storage stability. Years of experience have shown that the storage stability of latexes thickened with cellulosic thickeners is superior. No matter how is the pH value situation, the latex paint could maintain a uniform viscosity and pigment suspension for a long time.

♦ Anti-sagging. The stresses that occur during the coating process damage the hydration layer established between the thickener and the water. And Once the coating has ended, the latex paint will regain its viscosity and the sag will be prevented.

♦ Stable Viscosity of different PH value. Thickened latex paint with a cellulose-based thickener, the viscosity is stable among a wide PH range (3-11)

♦ Remain Adhesion. Cellulose thickener as a film-forming material, could merge together with latex paint. As long as the choice of latex paint is correct, it could well covered the pigment particles, cellulose-based thickener won’t have any loss of its adhesion.






Should be stored in a cool and dry place and protected against moisture.Storage temperature should be less than 30 Deg.C as risk of caking.

Do not stack pallets too high to avoid compaction. It is recommended to use these products within six months of purchase.

When you can’t use out the goods on time, please seal it again.
