Arc-Resistant GPO3 Fiberglass 90° Angles

Color: Red
Max. Temperature: 265° F
Tensile Strength: 10,000-15,000 psi (Good)
Impact Strength: 8.2-12 ft.-lbs./in. (Excellent)
Hardness: See table
For Use Outdoors: No
Specifications Met: UL 94 V-0

Because these GPO3 fiberglass 90° angles are arc and track resistant, they are often used for electrical applications in humid environments. They offer better electrical insulation properties than FRP fiberglass. Made of fiberglass-reinforced polyester, they're also called polyester-grade industrial laminate.
