Product Description
Hydroxyethyl Cellulose for Building Product Water Retention
Hydroxyethyl Cellulose is specifically formulated to enhance water retention in building products, providing superior performance in construction applications.
Company Profile
Shanghai Prior Chemical Scientific And Technical Co. LTD. (Grade A Tax Credit) was established in 2016. Leveraging China North Industries Group Corporation (NORINCO GROUP) resources, the company trades military-industrial materials including hydroxyethyl cellulose (HEC), hydroxypropyl methyl cellulose (HPMC), sodium carboxymethyl cellulose (CMC), ethyl cellulose (EC), and nitrocellulose (NC).
The company independently manufactures integrated nail-fastening products and holds equity in ammonium carboxmethyl cellulose (CMC-NH4) production and marketing. It holds nearly 70% domestic market share in HPMC for automotive exhaust honeycomb ceramics.
Hydroxyethyl Cellulose Introduction
Hydroxyethyl cellulose is a white or pale yellow, odorless, non-toxic, fibrous or powdered solid. It is prepared by the etherification reaction of alkaline cellulose and ethylene oxide (or chloroethanol). It belongs to the class of nonionic soluble cellulose ethers.
Key Properties
- Soluble in hot or cold water without precipitation at high temperatures or boiling
- Wide range of solubility and viscosity characteristics with non-thermal gelation
- Non-ionic nature allows compatibility with other water-soluble polymers, surfactants, and salts
- Water-retaining capacity twice that of methylcellulose with excellent flow control properties
- Highest protective colloid capacity among cellulose derivatives
Applications
Hydroxyethyl cellulose serves as an adhesive, surfactant, colloid protective agent, dispersant, emulsifier, and dispersion stabilizer across multiple industries:
- Pharmaceuticals: Thickener, protective agent, binder, stabilizer in emulsions, jellies, ointments, and tablets
- Textiles: Sizing agent in textile industry applications
- Oil & Gas: Thickener and fluid loss reducer in water-based drilling and completion fluids
- Construction: Cement retarder and moisture retainer in building materials
- Coatings: Thickener for latex in paint industry applications
- Multiple Industries: Printing, dyeing, papermaking, medicine, food, tobacco, pesticides, and fire extinguishing agents
Product Type Designation
Hydroxyethyl Cellulose product types are designated by application field code and viscosity specification code (e.g., D 3000).
Application Field Codes
- D: Latex paint industry
- C: Daily-use chemical industry
- B: Construction, painting, oil drilling, chemical industry
