Application

Poly(ethylene oxide) can be used:
  • As a starting material to fabricate double layer nanodiamond thin film that acts as an interfacial protection layer for Li anodes.
  • To enhance the surface properties of low-density polyethylene (LDPE) using plasma-initiated grafting.
  • To prepare hydroxyapatite/poly(ethylene oxide)nanocomposites.

Features and Benefits

  • High molecular weight (~300,000 Mv) offers excellent film-forming and thickening properties, ideal for controlled viscosity in formulations.
  • Offered in powder form for easy to handle, measure, and dissolve, ensuring consistent dispersion in aqueous systems.
  • Contains BHT as inhibitor to prevent oxidative degradation hence longer shelf life
  • Hydroxyl terminated- Provides reactive end groups for potential chemical modifications or cross-linking in advanced applications.
  • Suitable for thermal processing without compromising structural integrity.
