Epoxy Glass Fiber Laminate Fr4 Sheet

Epoxy Glass Fiber Laminate Fr4 Sheet

Solution Information
FR4 is a fireplace rated electrical-quality, dielectric fiberglass laminate epoxy resin technique combined with a glass material substrate.
The abbreviation “FR4” means: F (for flame) and R (for retardant).
FR4 grades substance supply superb chemical resistance, flame ratings (UL94-VO) and electrical properties below dry and humid circumstances. FR4 also characteristics higher flexural, effect, excellent mechanical toughness and bond energy at temperatures up to 130°C.
