    Fire Retardant Low Smoke GPO3 Fiberglass Sheet RoHS

    GPO-3 laminated material recognized by RoHs and Reach


    Introduction of GPO-3

    GPO-3 is insulation sheet which was composited by polyester resin , aluminium hydroxide and glass fiber mat , so it has high strength on mechanical and electrical . GPO-3 also called UPGM203 because different standard of area with different name .For example , persons in USA called it GPO-3 due to according to NEMA grade ; and persons in Europe called it UPGM203 due to according to standard of IEC , but they are same raw material . It is alkali-free fiberglass mat coated with unsaturated polyester resin as the reinforce material , then pressed the sheet under high temperature into rigid sheet as insulation sheet. It has good electrical property under high humidity and high mechanical property under room temperature , actually , it has very nice mechanical when it running in F grade temperature . it has been used in so many electrical equipments. In other way , it has fine fire retardant property and meet UL94-V0 and low smoke , good arc resistance and tracking resistance (CTI600) .

    Good arc resistance property means not easy to carbonization when impact by arc , as we known if the material is carbonization , insulating strength has been decreased . so it is the safety material. It's widely used in the low voltage electrical industries such as making of insulating sheet in UPS , top cover and bottom cover in transformer .


    characteristic of GPO-3 material

    1.Low smoke material when it is burning .

    2.Excellent fire retardant property and it meet UL94-V0

    3.Nice excellent heat resistance , temperature meets F grade .

    4. With very nice Comparative Tracking Index , it meets CTI≥ 600

    5. UL/ROHS/REACH recognized material .

    6.Excellent arc resistance ,it can bear 184 seconds.

    7.Good machining properties, it can be punched, drilled and cut by CNC .

    8. ROHS and REACH certified once a year by the third party .

    9.It is halogen free material and green product , very little effect to human body .
