lamina

G10

SmithLamina G-10 material is a continuous filament woven fibreglass sheet bonded with epoxy resin. The material has the ability to maintain excellent mechanical, electrical, and physical properties at elevated temperatures to 130C. NEMA G-10 is a non-brominated, non-flame retardant grade of glass epoxy laminate.

The industry refers to "G-10" material when they want a flame retardant, V-0 rated glass epoxy laminate rated at 130C 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.

The material is known to retain its high mechanical values and electrical insulating qualities in both dry and humid conditions. These attributes, along with good fabrication characteristics, lend utility to this grade for a wide variety of electrical and mechanical applications.
