Yellow Epoxy Fiberglass Cloth Laminate Sheet FR4

FR4 laminates is a fire rated electrical-grade, dielectric fiberglass laminate epoxy resin system combined with a glass fabric substrate.

The abbreviation "FR4" means: F (for flame) and R (for retardant), # 4 epoxy.

FR4 grades offer excellent chemical resistance, flame ratings (UL94-VO) and electrical properties under dry and humid conditions. FR4 also features high flexural, impact, superior mechanical strength and bond strength at temperatures up to 130°C. FR4 is suitable for structural, pc boards and electrical applications.
