Thermosets / PhenolicsG11

G11

High-temperature glass-epoxy laminate (Class H)

G11 is a thermoset laminate of woven fiberglass impregnated with epoxy resin, pressed under high pressure and temperature, with excellent mechanical and dielectric properties. It offers excellent thermal and chemical resistance and allows machining and continuous service up to thermal class H (180 °C), higher than G10/FR4. It is ideal for electrical and thermal insulation in machines and equipment that require very high temperature combined with high mechanical stress.
