    Electrical insulation material with high strength laminate polyester UPGM203 sheet


    Electrical insulation material with high strength laminate polyester UPGM203 sheet

    UPGM203 is also called GPO-3 , it is a glass reinforced thermoset polyester sheet material. GPO-3 with strong, stiff, dimensionally stable and impact resistant properties. The material also has excellent electrical properties including flame, arc, and track resistance. It is widely used for electrical insulating applications. GPO-3 is also used for mechanical applications where strength, stiffness, dimensional stability, and relatively low cost are required.

    Like many glass reinforced thermoset sheet materials, GPO-3 is somewhat abrasive on tooling during machining operations.

    Feature of this material as below :

    a. High mechanical & electrical strength

    b. Excellent rigidity & dimensional stability

    c. Excellent dielectric properties

    d. Very low water absorption

    e. Flame resistance ,it meet requirement of 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 .

    We would like to share application of this material as below :

    UPGM203 material (also called GPO-3) laminate sheet performs well in electrical applications that with properties of high arc and carbon track resistance as well as flame resistance, physical strength and moderate heat resistance. GPO-3 materials laminate is used extensively in the making of phase and end barriers, insulating supports, bus bar supports and mounting panels in switch gear and other types of electrical apparatus.

    With the development of electrical industry , GPO-3 material will more and more extensively used in it .
