Hydroxyethyl Cellulose (HEC) is a colorless or pale yellow, flavorless, and safe fibrous or powdered solid. It is produced through a chemical reaction that involves alkaline cellulose and either ethylene oxide or chloroethanol. This reaction results in a non-ionic, soluble cellulose ether that is non-toxic and easy to dissolve.
Product Description
In the world of modern industry, Hydroxyethyl Cellulose (HEC) stands as a versatile and indispensable material, finding applications in a wide range of sectors. HEC has earned its reputation for being a reliable solution in petroleum exploitation, coating, construction, medicine and food, textile, papermaking, and polymer polymerization. Its remarkable properties, including thickening, suspension, dispersion, emulsification, adhesion, film formation, water protection, and protective colloid, make it a valuable asset in various fields.
As a manufacturer specializing in Hydroxyethyl Cellulose (HEC) powder, we take pride in providing high-quality solutions that play a pivotal role in improving the performance and durability of building concrete. HEC is a versatile and essential additive that brings several benefits to the construction industry, ensuring the success of various projects.

1. Exceptional Solubility and Viscosity
One of the remarkable characteristics of HEC is its ability to dissolve in both hot and cold water, even in high-temperature or boiling conditions, without precipitation. This wide range of solubility and viscosity properties makes it a versatile choice in various applications. Moreover, HEC exhibits non-thermal gelatability, further expanding its utility.
2. Non-Ionic Nature and Compatibility
HEC is inherently non-ionic, which means it doesn't carry an electrical charge. This unique feature allows it to coexist harmoniously with a wide array of other water-soluble polymers, surfactants, and salts. In essence, HEC serves as an excellent thickener in high-concentration dielectric solutions, demonstrating its versatility in diverse industrial settings.
3. Superior Water Retention
When it comes to water retention, HEC outperforms other cellulose derivatives like methyl cellulose. Its water retention capacity is approximately twice as high, making it a valuable choice in applications where moisture regulation is crucial. This property also contributes to better flow control in various processes.
4. Dispersion and Protective Colloid Abilities
While HEC may not have the best dispersion ability compared to other cellulose derivatives like methyl cellulose and hydroxypropyl methyl cellulose, it boasts the strongest protective colloid capability. This means that HEC can effectively prevent the undesirable agglomeration of particles in suspensions, ensuring stable and consistent results in numerous applications.
These unique properties highlight HEC's versatility and effectiveness in various industries, making it a sought-after ingredient for a wide range of applications, from pharmaceuticals to construction and beyond.
1. Improved Workability
HEC enhances the workability of concrete mixtures. By adding HEC, the concrete becomes easier to handle and manipulate during construction. This improved workability ensures that concrete can be poured, placed, and finished more efficiently.
2. Enhanced Water Retention
Our HEC products are designed to have excellent water retention properties. This means that the concrete maintains the right level of moisture throughout the curing process, preventing premature drying and ensuring optimal strength development.
3. Reduced Segregation and Bleeding
HEC minimizes the risk of segregation and bleeding in concrete. Segregation occurs when the heavier aggregates separate from the cement paste, while bleeding involves the migration of excess water to the surface. HEC helps maintain a homogeneous mixture, reducing these issues.
4. Increased Adhesion
Our HEC powder promotes better adhesion between the concrete and other construction materials, such as reinforcement bars or formwork. This results in stronger, more durable structures that can withstand various environmental conditions.
5. Controlled Set Time
HEC allows for better control over the setting time of concrete. This is especially valuable in projects where precise timing is crucial, such as large-scale constructions or in hot weather conditions.
6. Enhanced Strength and Durability
By improving the overall quality of the concrete mix, HEC contributes to higher compressive strength and long-term durability of concrete structures. This ensures that the buildings and infrastructures built with our HEC-enhanced concrete stand the test of time.

Secure Packaging
HEC is typically packaged in sacks, with each sack containing 25 kilograms of the product. This packaging configuration is designed to ensure convenience and ease of handling, both during transport and storage.
Protection Against Moisture and Damage
To maintain the integrity and quality of HEC, it is essential to protect it from moisture and potential damage to the packaging during transportation. Moisture can adversely affect the properties of HEC, such as its solubility and viscosity. Therefore, it is advisable to store and transport HEC in a dry environment and take precautions to shield it from any moisture exposure.
Ideal Storage Conditions
For long-term storage, HEC should be kept in a cool and dry environment. Storing it in a place with controlled temperature and humidity levels will help prolong its shelf life and maintain its effectiveness. Adequate storage conditions are essential to ensure that the product retains its desired properties.
Extended Storage Life
Under proper storage conditions, Hydroxyethyl Cellulose has a storage life of up to two years. Adhering to recommended storage guidelines not only ensures the longevity of the product but also guarantees that it remains suitable for various applications across industries.
By following these packaging and storage instructions, you can ensure that HEC remains in optimal condition and ready for use when needed, whether in the petroleum industry, construction, pharmaceuticals, or any other application where its unique properties are valued.
