    Electrical insulation material laminate polyester UPGM203 sheet

    Product Introduction of UPGM203 materals

    UPGM203 laminate sheet also known as GPO-3, it is alkali-free fiberglass mat dipped into unsaturated polyester resin adding relevant chemical agent as the basic material pressed under high temperature PRESS into rigid panel as insulating material. It has good electrical property under high humidity and high mechanical property under medium temperature, nice fire retardant property, good arc resistance and tracking resistance. It's widely used in the low voltage electrical industries such as making of phase and end barriers, insulating supports, bus bar supports and mounting panels in switch-gear and other types of electrical apparatus.


    Feature of this UPGM203 as below

    a. High mechanical & electrical strength

    b. Excellent rigidity & dimensional stability

    c. Excellent dielectric properties

    d. Low water absorption

    e. Flame resistance ,UL94-V0

    f. Tighter thickness tolerance

    g. Flat and straight sheet

    h. Smooth and clean surface.

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