PEO(Polyethylene Oxide)

PDF CONTACT SAMPLE

Feature

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.
