Epoxy Machinable Board

Epoxy Board

Our range of technical composites based on fibreglass and epoxy resin allows us to offer you a complete selection of solutions up to a maximum temperature of 350°C.

These technical composites offer full thermal and electrical insulation. In addition to controlled flammability, they offer arc protection and can be used wherever temperature resistance, dimensional stability and mechanical resistance are essential parameters.

Furthermore, we have endeavoured to make not only strong materials, but also excellent workability in order to guarantee easy mechanical work with conventional tools.

Main properties of machinables Epoxy Boards

  • Low thermal conductivity
  • Very good resistance to high temperatures
  • Excellent dimensional stability
  • Sealing properties
  • High Resistance
  • Good mechanical resistance
  • High dielectric strength
  • High resistance to wear
  • High compressive strength

Applications of Glass/Epoxy Boards

  • Electrical insulators for induction systems
  • Static electrical insulators for power plants
  • Construction of electric, induction and arc furnaces
  • Flat seals and sealing organs
  • High frequency welding techniques
  • Press tray insulation
  • High-voltage equipment
  • Heating elements

Our range of machinable Epoxy Boards

E-6000

220°C continuous temperature and 320°C peak temperature. Laminate made from glass mat and beige/white epoxy resin. This product combines a low thermal conductivity (0.25 W/mK) and a low density, which enables the production of thinner and lighter insulation.

E-60

260°C continuous temperature and 330°C peak temperature. Laminate made from glass roving and brown epoxy resin. This product is mechanically and thermally more efficient than the E-6000 but less efficient as thermal insulation.

E-70

Laminate made from fibreglass and epoxy resin. This product is intended for high-temperature applications up to 350°C.
