G11 panel owns the character of high temperature resistance,High-intensity,Flame-retardant grades to UL94-V0,high mechanical properties

and dielectric properties,good heat resistance, good-smoothness, etc. is the most stable one of the insulation board materials.

G11 panel is electrical alkali-free glass woven fabric base impregnated epoxy resin binder by processing under pressure and heat. G10 added

with  flame retardants agent comes FR-4

G11 panel is accordance with the following international standards:

IEC60893 EPGC201/NEMA LI-1:G10/DIN 7735 HGW 2372/BS 3953 EP-3
