Technical Composite : Glass-Epoxy

Overview: Glass-Epoxy Technical Composite

Final Advanced Materials works with a range of glass fibre- and high-performance epoxy resin-based technical composites. These products are suitable for a wide variety of high-temperature applications. 

Glass-epoxy composites provide impeccable thermal and electrical insulation. Their combustibility is controllable, and they can be ideally deployed in applications where high-temperature resistance, dimensional stability and mechanical strength are essential. 

Manufacturing

This product is a composite material, comprised of a glass-fibre matrix and an epoxy resin. Epoxy, or polyepoxide, is a resin produced by the polymerization of epoxide monomers using a hardener. Curing is achieved by the action of heat.

Final Advanced Materials can supply these composite products in sheet material form, for your own designs. It is also possible for us to undertake the complete execution of your project in our specialized workshop.

Applications of Glass-Epoxy Technical Composite

  • Electrical insulators in induction systems
  • Static electrical insulators in power installations
  • Construction of electric furnaces, induction furnaces and arc furnaces
  • Flat gaskets and sealing components
  • High-frequency welding technology
  • Insulation of press plates
  • High-voltage switchgear
  • Heating elements

Main characteristics of Glass-Epoxy Technical Composite

  • Low thermal conductivity
  • Good high-temperature resistance
  • Excellent dimensional stability
  • Suitable for sealing applications
  • Exceptional toughness
  • Good mechanical resistance
  • High dielectric strength
  • Good wear resistance
  • High compressive strength

Available Glass-Epoxy Technical Composite

E-6000 : This product combines low thermal conductivity (0.25 W.m-1. K-1) with low density, thus permitting the production of more delicate and lightweight insulating components. It is resistant to a continuous temperature of 220 °C and a peak temperature of 320 °C. This material is laminated from a basis of glass-fibre matting and whitish-yellow epoxy resin. It shows good resistance to chemical agents.

E-60 : This product delivers a superior mechanical and thermal performance to E-6000, but is less effective as a thermal insulator. It is resistant to a continuous temperature of 260 °C and a peak temperature of 330 °C. It is laminated from a basis of grey-coloured glass roving and epoxy resin.
