UPGM203 UNSATURATED POLYESTER GLASS MAT SHEET(GPO-3)
Product Instruction
UPGM203/GPO-3 is a glass reinforced thermoset polyester sheet material. GPO-3 is strong, stiff, dimensionally stable, and impact resistant. The material also has excellent electrical properties including flame, arc, and track resistance. It is widely used for electrical insulating applications
Compliance with standards
IEC 60893-3-5:2003
Application
Its most common use is to support and electrically isolate power and electrical distribution equipment. GPO-3 applications include bus bar supports and mounting panels and high-voltage appliance insulators.
