G5/G9 Melamine Tube, G5/G9 Tubes Glass Reinforced Melamine
G5/G9 Melamine Tube is composed of a continuous glass woven cloth base impregnated with a melamine resin binder. Melamine is the hardest of all laminates, exhibiting good dimensional stability and arc resistance. It is also caustic resistant.
G9 is compliant with MIL I 24768/1, Type GME. G5 material is compliant to MIL I 24768/8 Type GMG. The two melamine sheet materials are very similar except that the G-9 material has higher resiliency to harsh and adverse environments than the G5. In most cases, the G-9 can be substituted for the G-5.
The G9 material has high strength and excellent arc resistance and electrical insulating properties which allows it to be used as a mechanical support in electrical equipment, switch gear, and slot wedges where Class “B” insulation is required.
Out of all the thermostat laminates, Melamine is the hardest material making it extremely stable and rigid.? G-9 material is also resistant to most harsh chemicals. G9 maximum operating material is 285° F.
(Melamine resins, once cured, are the hardest, most rigid, and abrasion resistant of the standard resins employed in the production of industrial laminates. However, prolonged exposure to high temperatures can adversely affect its mechanical and electrical strength properties. Arc resistance, however, may remain unaffected despite excessive thermal exposure.) Melamine are the hardest of laminates, exhibiting good dimensional stability and arc resistance. It’s also caustic resistant. A key difference between NEMA Grades G5 and G9 is that G9 is more resistant to the elements of the environment. Thus, G9 can be safely substituted where G5 is called for NEMA G-5 MIL-I-24768/8 GMG, IEC 60893-3 Type 3 MF GC 201 .
