Functions

  • Water-soluble thermoplastic resin.
  • Also soluble in various organic solvent.
  • Nonionic.
  • When dissolved, the solution shows high viscosity even at low density, making PEO an effective thickener.
  • Products with high-molecular weights have dispersing and coagulation properties.
  • Thermoplastics, so PEO can be used for extrusion molding, foundry molding, and calendaring molding.
  • Cannot be broken down by bacteria.
  • Aqueous solution reduces friction resistance.
  • Forms associated molecules with chemical compounds with high polarity such as urea, acrylic resin, and phenol resin.

PEO is a high-polymer polyethylene oxide with molecular weights ranging from 150,000 to 10 million, and is created through the polymerization of ethylene oxide.

PEO can be used in a wide range of industrial application.
