Hydroxyethylcellulose HEC CAS No. 9004-62-0

Overview of Hydroxyethylcellulose HEC?

Hydroxyethyl cellulose is a non-ionic ether prepared from natural polymer cellulose through chemical processes. It is an odorless, tasteless, non-toxic white powder or particle that can be dissolved in cold water to form a transparent viscous solution, which is not affected by pH. It has the properties of thickening, bonding, dispersion, emulsification, film formation, suspension, adsorption, surface activity, water retention, and salt resistance.

Physical and chemical properties of Hydroxyethyl Cellulose HEC Powder

1. HEC powder is soluble in hot water or cold water, and high temperature or boiling does not precipitate, so HEC powders have solubility and viscosity properties and are non-thermal gelatinizing;

2. Hydroxyethyl cellulose is non-ionic and can co-exist with other water-soluble polymers, surfactants and salts over a wide range.

It is an excellent colloidal thickener for solutions containing high concentrations of dielectrics;

3. HEC has twice the water-holding capacity of methylcellulose, providing better flow regulation;

4. HEC has the least dispersing ability but the most colloid-protecting ability compared to the recognized methylcellulose and hydroxypropylmethylcellulose.

Hydroxyethyl Cellulose Uses in Concrete

Hydroxyethyl cellulose (HEC) is a nonionic cellulose ether that plays an important role in concrete admixtures due to its unique physicochemical properties.

1)Thickening effect

Hydroxyethyl cellulose has good thickening ability and can increase the viscosity of the concrete mix, thus improving its stability. This thickening effect makes the concrete easier to operate and control in the construction process, reducing the possibility of material separation and water secretion.

2) Water retention effect

In concrete, hydroxyethyl cellulose can effectively lock the water to prevent water from evaporating too quickly. This not only ensures the working performance of concrete in the initial setting process but also helps to reduce cracks on the surface of the concrete, thus enhancing its durability.

3) The role of retardation

Hydroxyethyl cellulose also has a certain retardation effect and can extend the initial setting time of concrete, providing more flexibility for construction.HEC is particularly important in the need for a longer period for concrete pouring and shaping projects.
