    EN45545 heat resistant Red GPO3 Fiberglass Sheet

    Made in China GPO-3 laminated material recognized EN45545 and UL


    Destripation of GPO-3

    GPO-3 also called UPGM203 , different standard of area with different name , but the same raw material . Material composition of it is glass fiber and polyester resin . 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 medium temperature , it has been used in so many electrical equipment current . In other way , it has fine fire retardant property and meet UL94-V0 , good arc resistance (arc resistance meet 184 second) and tracking resistance (CTI600) , good arc resistance property means no easy to carbonization when impact by arc , as we know 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 .

    Features of GPO-3

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

    2.Excellent heat resistance ,temperature meets 155℃

    3.Good impact resistance on mechanical and electrical , especially on arc impact .

    4. UL recognized

    5.Excellent arc resistance ,it can meet 184 second

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

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

    8.It is fire inflaming retarding material , it meet requirement of UL94 V-0 standard

    9.Halogen free material
