SmithLamina G-11 material is a formable, high strength medium weaves glass epoxy composite that retains fifty percent of its original properties at 155�C (Class F). Typical applications include insulation in power generation equipment and other structural part.

The industry refers to "G-10" material when they want a flame retardant, V-0 rated glass epoxy laminate rated at 130�C RTI. Technically, NEMA G-10 is a non-flame retardant, non-brominated version of glass epoxy laminate. If a non-brominated material is required, please specifically address this issue.

It has excellent mechanical strength and electrical properties at elevated temperatures. It has a continuous operating temperature of 329�F.

The mechanical and electrical properties of G-11 are excellent. Even at elevated temperatures, G-11 has a low dielectric loss and has retention of 50% of mechanical properties at 300 degrees F. Because of these characteristics, this material should be used in applications where temperatures in excess of 125 degrees C are encountered.

Today, G-11 is used in many unrelated applications including high temperature, cryogenic, and radiation.
