Poly(ethylene oxide) [MW 600,000], also known as PEO, is a high molecular weight, water-soluble polymer used in viscosity modification, film-forming systems, lubricity enhancement, coatings, dispersions, and specialty aqueous formulation work.
Synonyms / related names: PEO; poly(ethylene oxide); polyethylene oxide; polyoxyethylene; polyethylene glycol polymer.
With a molecular weight of approximately 600,000, this PEO grade is useful in applications where water solubility, rheology control, flow modification, and polymer compatibility are important. Its higher molecular weight can support viscosity build, thickening behavior, and film formation in aqueous and solvent-compatible systems.
Researchers, formulators, and industrial users may use poly(ethylene oxide) in coatings, lubricants, flocculant and dispersant systems, aqueous thickening systems, hydrogel-related materials research, and additive manufacturing formulation studies.

Solubility & Compatibility Considerations
- Soluble in water and selected organic solvents
- Soluble in acetone, alcohol, chloroform, toluene, and dichloromethane
- Higher molecular weight PEO can significantly influence viscosity and flow behavior
- Hydration and final viscosity depend on concentration, mixing method, temperature, shear, and rest time
- Compatibility should be evaluated with salts, additives, pigments, fillers, solvents, and other formulation components before scale-up
- Formulation performance depends on molecular weight, polymer concentration, processing conditions, and intended end use
Final performance should be confirmed under the user’s specific formulation and processing conditions, including polymer concentration, solvent system, mixing order, temperature, and application requirements.
Preparation Tips
- Add gradually to the liquid phase with adequate mixing to reduce clumping
- Allow sufficient time for full hydration and viscosity development
- Avoid excessive dust generation during powder transfer
- Use clean equipment to reduce contamination during solution preparation
- Run small-scale compatibility and viscosity trials before production or process transfer
Handling & Storage
