Product Description

NEMA G-11  G11
Epoxy Glass Cloth Laminate Sheet
REF: IEC6089-3-2 EPGC203 / NEMA G-11 certs to MIL-24768/3 GEB / Hgw-2372.4. DIN-7735
                                      
 

1.FEATURES

• Very low hygrometric susceptibility
• Good dielectric properties
• High resistance to friction
• Small losses at high frequency
• High resistance to flame ( V-0 )

  

2.APPLICATIONS

Very convenient for equipment on high frequencies and generally for all elements having to bear strong
dynamic stresses with good resistance to fatigue. It can be used at fairly high temperatures ( more than 155 ^OC ).
