1. COMPOSITION AND PRESENTATION
FUWANG FR4 is a stratified insulator made from fibre glass fabric and epoxy resin with improved
resistance to flame ( V-0 ).
At delivery time the presentation of the sheets is as follows:

- Maximum sizes: 1020 X 1220 mm

- Thickness: From 0.13 mm 50 mm

- Colour: Light Green / Natural / Black / Brown / Red / Orange / Yellow / Green / Blue / Purple / Ash

/ White / Carbon or based on the users special color.

- On demand we can deliver strips or finished components

- Surfaces: Shining

2. APPLICATIONS.

Very convenient for equipment for high frequencies and in general for all elements put under high dynamic stresses with high resistance to fatigue, can also be used extensively for test instrucments of PCB, and sports equipment.
