Insulation material GPO-3(UPGM203) meet ROHS/REACH and with certificate of UL
GPO3 fiberglass reinforced polyester sheet, known as UPGM203,are manufactured using polyester resin and fiberglass mat under high temperature.
GPO-3 fiberglass reinforced polyester 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 UP GM 203 fiberglass reinforced polyester sheet products are UL recognized , we are the GPO-3 material manufacturer in China , this material has been supplying to many end user who is top500 and industry leader corporation .
Thickness tolerance will be better than IEC , even if the thickness tolerance must be met ±0.2mm by 20mm , we can do it by low production cost .
Feature of GPO3
It has nice properties on fire resistance , according to certificated by UL , it meets UL94-V0;
It has nice electrical properties , it meets CTI600
GPO-3 sheet can be easily machined by CNC
It has property on arc resistance , the test value is more than 180 seconds
It is the green product and have already passed the recognized by RoHs and Reach.
It is the customized products can be machined as per client’s drawings
