CELLULOSE ETHER
Enx Energy and Chemicals Nigeria Limited, is the leading chemical supplier in Nigeria. We supply Cellulose ether in large quantities.
Cellulose ether are a major class of commercially important water-soluble polymers for the construction and building industries. Cellulose ethers are capable of increasing the viscosity of aqueous media. The viscosity ability of a cellulose ether is primarily controlled by its molecular weight, chemical substituents attached to it, and conformational characteristics of the polymer chain.
SPECIFICATIONS
| Type | Hydroxylethyl Cellulose(HEC) |
| Package | 25kg |
APPLICATION
For construction products, cellulose ethers act as thickeners, binders, film formers, and water-retention agents. They also function as suspension aids, surfactants, lubricants, protective colloids, and emulsifiers.

Details |
Advantages |
| Binding | Used as high-performance binders for extruded fiber-cement materials | Green strength |
| Emulsification | Stabilize emulsions by reducing surface and interfacial tensions and by thickening the aqueous phase | Stability |
| Film formation | Form clear, tough, flexible water-soluble films | •
Excellent barriers to oils and greases • Films can be made water-insoluble via cross-linking |
| Lubrication | Reduce friction in cement extrusion; improve hand-tool workability | •
Improved pumpability of concrete, machine grouts, and spray plasters • Improved workability of trowel-applied mortars and pastes |
| Nonionic | Products have no ionic charge | •
Will not complex with metallic salts or other ionic species to form insoluble properties • Robust formulation compatibility |
| Solubility (organic) | Soluble in binary organic and organic solvent/water systems for select types and grades | Unique combination of organic solubility and water solubility |
| Solubility (water) | •
Surface-treated/granular products can be added directly to aqueous systems • Untreated products must first be thoroughly dispersed to prevent lumping |
•
Ease of dispersion and dissolution • Control of solubilization rate |
| pH stability | Stable over a pH range of 2.0–13.0 | •
Viscosity stability • Greater versatility |
| Surface activity | •
Act as surfactants in aqueous solution • Surface tensions range from 42 to 64 mN/m |
•
Emulsification • Protective colloid action • Phase stabilization |
| Suspension | Control settling of solid particles in aqueous systems | •
Antisettling of aggregate or pigments • In-can stability |
| Thermal gelation | Occurs to aqueous solutions of methyl cellulose ethers when heated above a particular temperature | •
Controllable quick-set properties • Gel go back into solution upon cooling |
| Thickening | Wide range of molecular weights for thickening water-based systems | •
Range of rheological profiles • Pseudoplastic shear thinning rheology approaching Newtonian • Thixotropy |
| Water retention | Powerful water-retention agents; keep water in formulated systems and prevent loss of water to atmosphere or substrate | •
Highly efficient • Improved workability and open time of dispersion-based systems such as tape joint compounds and aqueous coatings, as well as mineral-bound building systems such as cement-based mortars and gypsum-based plasters |
