Comco-Glass hard fabric

Comco EPP Produkte - Glashartgewebe

A thermoset material made of glass fabric or glass roving fabric as a carrier material and polyester, epoxy, melamine or silicone resins as binders. This group of materials is characterised by high mechanical strength and excellent electrical insulation properties. These materials are used in many areas such as switchgear construction, traffic engineering, vehicle construction, plant engineering and medical technology.

Standard colours: white, green, red, beige

Material properties:

  1. very good mechanical and dielectric properties
  2. high-voltage applications in oil and air

Application examples:

  • rail holders
  • insulating strips
  • sleeves
  • cable covers

Sheets: Sizes: 2800 x 1220 mm and 2150 x 1220 mm standard (tol. +/-).
Other formats also available.

Thicknesses: 0,2-150 mm
