Product Introduction:
UPGM203 is also called GPO-3 , it is a glass reinforced thermoset polyester sheet material. GPO-3 have good mechanical strength ,dielectric strength and excellent arc and carbon tracking resistance ,grade GPO3 is flame resistant.it is designed for general purpose insulation and mechanical support in electrical equipment ,where a flame resistant material is required.
Like many glass reinforced thermoset sheet materials, GPO-3 is somewhat abrasive on tooling during machining operations.
Feature of this GPO-3 as below :
(1)Good electronic performance under high temperature,good performance for anti leakage of electronic
(2)Arc resistence could reach more than 180°C
(3)flame-retardant grade could reach 94-V0, thermal endurance class could reach F grade(More than 160°C)
(4)It is the advance retardant ,anti-impact and anti corrosion material in these recent years
