Consisting of electrical grade epoxy resin systems combined with a variety of glass fabric substrates, these products come in low and high temperature versions. Low temperature thermoset epoxy/glass materials offer good chemical resistance and electrical properties under dry and humid conditions.
Some systems are flame retardant and meet the Underwriters Laboratories Flammability Class, V-0. They also feature high flexural, impact, and bond strength at temperatures up to 130°C. These fiberglass composite materials are suitable for a variety of structural, electronic, and electrical applications.
High temperature fiberglass epoxy resin systems offer superior mechanical strength and insulative properties over a wider temperature range. These products feature high mechanical strength at continuous operating temperatures up to 180°C in mechanical applications. In response to customer requests, Norplex-Micarta can change the resins to enable products to withstand even higher continuous operating temperatures. Several standard grades can handle temperatures much higher than 180°C for short periods of time.
At elevated temperatures up to 155°C, epoxy composites retain at least 50 percent of their room temperature flexural strength. Several types meet NEMA G-11 requirements, and the materials can also be produced on any glass style for applications that do not require NEMA G-11. Applications include solder pallets, corona dissipation, rotor slot cell insulation, and structural applications at elevated temperatures.
