  • Synthesize polymer electrolytes for solid-state batteries and fuel cells.
  • Prepare biodegradable PEO/Ag nanocomposites forbiomedical and food packaging applications.

Features and Benefits

  • High water solubility
  • Non-toxicity
  • Rapid hydration
  • Insensitive to pH of the physiological system

General description

Poly(ethylene oxide) is a non-ionic hydrophilic linear polymer. It can be prepared by catalytic polymerization of ethylene oxide. Owing to its hydration and swelling properties, it is widely used in controlled drug delivery systems and bioadhesive materials.
We are committed to bringing you Greener Alternative Products, which adhere to one or more of The 12 Principles of Green Chemistry. Polyethylene glycol (PEG) is an eco-friendly, biodegradable polymer widely used in pharmaceuticals and cosmetics. Its non-toxic nature and versatility make it a sustainable choice, derived from renewable resources, contributing to greener product formulations. Click here for more information.
