Multipurpose Flame-Retardant Garolite G-10/FR4 Rectangular Tubes

Color: Green
Maximum Temperature: 265° F
Tensile Strength: 32,000-40,000 psi (Excellent)
Impact Strength: 5.5-12 ft.-lbs./in. (Excellent)
Hardness: Rockwell M100 (Extra Hard)
For Use Outdoors: Yes
Specifications Met: MIL-I-24768/27

These rectangular tubes are flame retardant, machinable, and electrically insulating. They’re made of epoxy resin, making them good for use with printed circuit boards, insulating washers, and transformer components. With low moisture absorption, these tubes are often used as thermal insulators. Made with fiberglass fabric reinforcement, they’re strong and easier to machine than other glass cloth phenolics. Garolite G-10/FR4 is also called epoxy-grade industrial laminate and phenolic.

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.
