G5 G9 Melamine Glass Sheet MFGC201 HGW2272 Insulation Laminate

product details

Description

G-5 and G-9 Composite laminate is a continuous filament glass cloth with heat resistant melamine resin binder. G9 glass melamine laminate is a very hard, flame resistant grade that has excellent arc resistance and electric strength properties even under Humid or wet conditions. G-5 and G-9 laminate sheet has high mechanical strength and machines well. This product also has good dimensional stability.

G-5 and G-9 are typically discussed together as one. Both materials consist of woven glass fabric and a melamine resin base. Both materials offer outstanding electrical properties in high humidity environments. Both materials have essentially the same mechanical properties. 

The most significant difference is that the G9 offers improved resistance to the elements of the outdoors.  G9 can safely be substituted for G5.
