Polymer Distribution
Evonik NANOPOX® F 520 Nanosilica
Categories: Ceramic; Oxide; Silicon Oxide

Material Notes: NANOPOX® products are high-performance concentrates of nanosilica in epoxy resins and have been specially designed for fiber-reinforced composite applications. The silica phase consists of surface modified SiO2 nanospheres with a defined size of 20 nm and a very narrow particle-size distribution. NANOPOX® products are used to replace part of the epoxy resin in existing formulations, typically in the range of 20—30%. Some applications, however, require higher concentrations of nanosilica. They can be blended with all commercially available epoxy resins and cured with all commercially available hardeners. Introducing nanosilica in the epoxy formulation improves various properties of the fiber-reinforced composite part
  • increased strength, modulus, and hardness
  • improved toughness (fracture energy, fracture toughness, impact resistance)
  • significantly improved fatigue performance
  • drastically increased compressive properties
  • no change in Tg
Using NANOPOX® products can significantly improve the performance of fiber-reinforced composite parts. Because the viscosities of NANOPOX® products and their blends are rather low; these materials are highly suitable for all infusion and injection processes. With a size of 20 nm, the silica particles penetrate even tightly meshed fabrics easily. As the particles are completely transparent, the NANOPOX® products can be used for visible parts as well. Using NANOPOX® F 631, UV-curable systems can be formulated. NANOPOX® FW 404, the aqueous emulsion of NANOPOX® F 400 is designed for fiber sizing applications. Just a thin layer of this material on the fiber surface is enough to improve the mechanical properties of the composite part.

Areas of Application:

  • ?pre-pregs
  • ?pultrusion, filament winding, pull winding, and so forth.
  • ?RTM, VARTM, VARI, and so forth.
