For economy plus wide versatility in both fabrication techniques and end usage, phenolic resins are often the most attractive. Epoxy resins have excellent electrical properties over a wide range of humidity conditions and thermal variations. For arc resistance, melamine resin is superior and offers excellent heat and flammability resistance.
Glass Fabric Base Laminates - Woven glass cloth can be combined with all of the common resin systems. Epoxy resin is the most popular for improved electrical properties, followed by melamine for arc resistance and by phenolic for heat resistance.
Paper Base Laminates - Norplex's paper base laminates are combinations of phenolic, melamine and epoxy resin systems combined with kraft or cotton linter papers. At times, cover sheets of specialty papers, vulcanized fiber, glass fabric pre-pregs, rubber and other surface plies are added.
