Halogen-Free Garolite G-10 Tubes

Color: Yellow
Max. Temperature: 265° F
Tensile Strength: 32,000-40,000 psi (Excellent)
Impact Strength: 5.5-9.5 ft.-lbs./in. (Excellent)
Hardness: Rockwell M100 (Extra Hard)
For Use Outdoors: No
Specifications Met: MIL-I-24768/2, UL 94HB

These Garolite G-10 tubes can be used in place of Garolite G-10/FR4 tubes for applications that are sensitive to halogen, such as in nuclear plants. They're strong, machinable, and electrically insulating. Made of an epoxy resin with fiberglass fabric reinforcement, Garolite G-10 is also called epoxy-grade industrial laminate and phenolic.
