GPO3 Electrical Red Fiberglass Sheet 1/4" Thick x 12.0" Wide x 36.0" Long

Description: GPO3 Electrical Red Fiberglass Sheet 1/4" Thick x 12.0" Wide x 36.0" Long Thickness: 1/4" Thickness Tolerance: +/-.015" Width Inch: 12.0" Length Inch: 36.0" NEMA GPO3 Mil-I-24768/6 IEC 60893-1, UP GM 203 UL File # E82624 Width Tolerances: +/- 1/8" Length Tolerances: +/- 1/8" GPO-3 Sheets are used in electrical applications that require high arc and carbon track resistance as well as flame resistance, physical strength, and moderate heat resistance. Fiberglass has internal stresses built up inside of the sheet. When a sheet is cut, it relieves that stress. As a result, the piece that is cut, especially for thinner sheets, warp and creep may occur in the center area of the sheet.Fiberglass has a balanced stress state with respect to the shape centerline. When Cutting to size, more material is removed from one side of the centerline than the other, the material will “dish up” towards the side with more material removed. The amount of residual stress locked into the material determines how much the material will move once the outer material is removed. The same condition exists in metals. However, the lower stiffness of fiberglass makes the magnitude of this more significant. General Information Unit ASTM/UL TEST NO.
