3240/G10/G11

Ref: EP-GC1. UNE-53189 Part 1. / Hgw-2372. DIN-7735 / G-10. NEMA LI-1 / GB-3240

1.  COMPOSITION AND PRESENTATION
FW-3240  is a stratified insulator made from fiber glass fabric and epoxy resin.

At delivery time the presentation of the sheets is as follows:
- Maximum sizes: 1980 X 980 mm; 1020 X 1220 mm. - Thickness: From 0.2 mm
- Color: Yellow / Light green - Surfaces: Shining
- On demand we can deliver strips or finished components. - Very low hygrometric susceptibility - Small losses at high frequency
- Excellent mechanical properties when cold - Good dielectric properties
- Workable while cold up to 3 mm thick

2.   PROPERTIES AND APPLICATONS

Very convenient for equipment on high frequencies and in general for all elements put under high dynamic stresses with high resistance to fatigue.
