Product Description

Product Description

Hydroxyethyl cellulose (HEC) is a white or pale yellow, tasteless, non-toxic, fibrous or powdery solid prepared by etherification of alkaline cellulose (or chloroethanol). It is a non-ionic soluble cellulose ether.  Because HEC has good thickening, suspension, dispersion, emulsification, adhesion, film formation, protection of water and provide protective colloid and other characteristics, has been widely used in oil exploitation, coating, construction, medicine and food, textile, paper making and polymer polymerization reaction and other fields.  Screening rate of 40 mesh ≥99%.

Application

1. This product is used for cracking method to extract polymerized dispersing agents such as oil water base gel fracturing fluid, polystyrene. Also for latex thickening agent in paint industry, hygristor in electronics industry, cement anti-coagulant agent and water retention agent in construction industry. Glazing in ceramic industry and toothpaste binder. Also widely used in many aspects such as printing and dyeing, textile, paper, pharmaceutical, health, food, cigarettes, pesticides and fire extinguishing agent.
2. Used as a water-based drilling fluids, and thickening agent and filtrate reducer of completion fluids, thickening agent has obvious effect on brine drilling fluid. Also can be used for filtrate reducer of oil well cement. Cross-linking with the polyvalent metal ions into a gel.
3. As surfactants, protective colloids, emulsion stabilizers in combination with emulsion , and a tackifier, dispersant, dispersion stabilizer of emulsion. Widely used in many aspects such as coatings, fibers, dyeing, paper, cosmetics, pharmaceuticals, pesticides. There are many uses in oil exploitation and machinery industry.
4. As surfactants, latex thickening agent, protective colloid, oil exploitation fracturing fluid and polystyrene ride dispersing agents, etc.
