Product Description

Used in construction and building materials:
Because of its strong water retention capacity, hec is an effective thickener and binder for cement mortar and mortar.
Adding it to mortar can improve the fluidity and construction performance,
Can prolong the evaporation time of water,
Improve the initial strength of concrete and avoid cracks.
Used for plastering plaster, bonding plaster, plaster putty can significantly improve its water retention and bonding strength.

Formula: C₂₉H₅₂O₂₁
CAS #: 9004-62-0
Synonyms: HEC, Natrosol 210HHX, Natrosol HIVIS 4465
Hydroxyethyl Cellulose (HEC) is a nonionic, fast hydrating, and ultra-high viscosity. HEC is used as viscosity and rheology modifier, water retention agent, stabilizer, and suspending agent in a varity of water-based fluid systems where a nonionic material is desired.

Applicated in cementing and oil drilling industries:
Drilling muds(low solids and brine fluids)
Drill-in -fluids
Spud muds(immediate viscosity)
Completion and workover fluids(Brine fluids)
Gravel packing
Spacers or flushes
Cutting injection
Fracturing fluids(suspension of proppants)

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. The use of Hydroxyethyl Cellulose thickening fluid easily acids, enzymes or oxidants decomposition, greatly improving the ability to recover hydrocarbons.
Fluid in the well, Hydroxyethyl Cellulose is used as proppant carrier. These liquids can be easily through the process of cracking
Hydroxyethyl Cellulose configuration using drilling fluid, based on its low solids content, can effectively increase drilling stability. These properties 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
