    Electrical insulation material laminate board fiberglass epoxy FR4

    Fiber glass epoxy FR4 sheet is a NEMA grade designation for glass-reinforced epoxy laminate material.
    Fiber glass epoxy FR4 sheet is a composite material composed of woven fiberglass cloth with an epoxy resin binder that is flame resistant (self-extinguishing).
    "FR" stands for flame retardant, and denotes that the material complies with the standard UL94V-0.
    FR4 sheet is a popular and versatile high-pressure thermal plastic laminate grade with good strength to weight ratios.
    With near zero water absorption, fiber glass epoxy sheet is most commonly used as an electrical insulator possessing considerable mechanical strength. 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.
     
    FR-4 with so many advantages as below :

    * High mechanical & electrical strength

    * Excellent rigidity & dimensional stability

    * Excellent dielectric properties

    * Low water absorption

    * Flame resistance ,UL94-V0

    * Tighter thickness tolerance

    * Flat and straight sheet

    * Smooth and clean surface.

    * Easy to machine by CNC , such as drill holes or grinded .

    Due to the High mechanical & electrical strength , this material have the widely application in every electrical equipments , such as below :

    Epoxy sheet FR-4 with the good properties on mechanical & electrical , this material is widely used high-end insulation parts processing, FPC (flexible printed circuit-board) reinforcement sheet, air gap , cover and base of transformer . planetary wheel, transformer insulation baffle, LV&MV voltage switch, precision test fixture, carbon film printing, electronic insulation parts, gasket,washer,various water sports equipment and blade-tool handle materials.

    If the color of epoxy sheet is yellow , it has the good property on ageing resistant , usually , it was used in out door electrical equipment . Out door with direct solar radiation , the normal material will be accelerated aging.
