Product Feature: G9 G5 melamine Tubes, The Melamines are the hardest of laminates, exhibiting good dimensional stability and arc resistance. It’s also caustic resistant. This grade tube is composed of a continuous glass woven cloth base impregnated with a melamine resin binder. Melamines are the hardest of all laminates, exhibiting good dimensional stability and arc resistance. It is also caustic resistant G-9 is a laminate sheet comprised of flame retardant melamine resin and woven fiberglass glass substrate. 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. (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.) 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 608 93-3 Type 3 MF GC 201, Normal temperature 180C, highest temperature: 260C 20 minutes, instant temperature 460C.
