G11 Glass Epoxy Characteristics

G11 grade glass epoxy laminate offers improved mechanical strength at higher temperatures than the G10 grade.

Because epoxy resins such as G11 laminate are virtually impervious to moisture, this material is a good choice of thermosets for fabricated components used in electrical and mechanical applications.

Glass cloth materials have outstanding mechanical and electric strength as well as good dielectric properties.

G11 offers:

  • Good dimensional stability
  • Outstanding insulating and electrical properties
  • Moisture resistance
  • Excellent flammability rating
  • UL listed

Applications for G11 Thermosets

  • Power generation components
  • High temperature applications
  • High humidity applications
  • Structural parts
  • Printed circuit boards & terminal boards
