HEC
Wholesale HEC Hydroxyethyl Cellulose
Product overview
Hydroxyethyl Cellulose (hydroxyethyl cellulose) is a non-ionic water-soluble cellulose ether, usually appearing white to pale yellow in powder form.
product characteristics
Good water solubility: it can be quickly dissolved in cold water to form a transparent and uniform solution.
Thickening and stabilizing effect: significantly increase the viscosity of the solution, improve the stability of the system, prevent precipitation and delamination.
Pseudoplastic fluid characteristics: the solution has a high viscosity at low shear rate, and the viscosity decreases at high shear rate, which is convenient for construction and application.
Salt resistance: It can still maintain good performance in a certain degree of salt solution.
pH stability: Stable performance over a wide pH range.
product use
Coatings field: As a thickening agent and rheological control agent, improve the construction performance and storage stability of coatings.
For example, in water-based architectural coatings, the paint is easy to paint and the coating is uniform and smooth.
Daily chemical industry: Used in shampoo, body wash, lotion and other products to increase consistency and stability.
Oil extraction: As an additive to drilling fluid and completion fluid, it plays the role of increasing viscosity and reducing filtration loss.
Pharmaceutical field: adhesive, suspension, etc., which can be used as tablets.
Production process
It is generally prepared from cellulose by etherification reaction with ethylene oxide.
Market prospects
With the increasing demand for high-performance additives in various industries, the market outlook for Hydroxyethyl Cellulose is very positive. Driven by the continuous development of environmentally friendly coatings, high-end daily chemical products and oil extraction technology, its market demand is expected to continue to grow.
use precautions
When storing should pay attention to moisture, sun protection, avoid contact with strong oxidants.
The solution should be stirred slowly to avoid clumping.
In different application systems, it is necessary to optimize the addition amount and use conditions according to the specific situation.
To sum up, Hydroxyethyl Cellulose, with its unique properties and wide range of uses, plays an important role in many fields, providing a strong guarantee for the improvement of product quality and performance.
