Laminated Gpo3 Sheet Excellent Electrical Property On CTI
Intr0duction of GPO-3 material
GPO-3 material , known as UPGM203 material , this material was produced by polyester resin and fiberglass mat under hot pressed.
GPO-3 sheet perform well in electrical application that require high arc and track resistance ,as well as flame resistance , physical strength and high heat resistance.
All our GPO-3 products are UL recognized and are used extensively in the making of phase and end barriers,insulating supports,bus bar supports,mounting panels in switch gear and other types of electrical equipment .
It is green material meet requirement of ROHS/REACH and have certificates for both .
Features of GPO-3
1.Flammability: UL94 V-0
2. CTI≥ 600V without tracking
3. Heat resistance is F Class
4.Excellent arc resistance> 180seconds
5.High mechanical strength and good Impact resistance
6.Good Processing properties, it can be punched, drilled, machined, cut.
7. UL certification passed ,ROHS once a year, have passed inspection
8.Complete sort, sufficient inventory to meet the different needs of customers
