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.

Arc-Resistant Garolite G-9 Angles

Color: Gray
Maximum Temperature: 280° F
Tensile Strength: 30,000-37,000 psi (Excellent)
Impact Strength: 5.5-7.0 ft.-lbs./in. (Excellent)
Hardness: Rockwell M120 (Extra Hard)
For Use Outdoors: Yes
Specifications Met: UL 94 V-0

Machine these angles into arc barriers, switch mounts, and components for circuit breakers and electrical equipment. They resist carrying electric currents in dry or humid areas, even when exposed to sudden electric discharge. Strong, they’re also good for making terminal boards and other structural parts. They won’t crack if hit, and they resist breaking while carrying heavy loads. Meets UL 94 V-0 for flame retardance.

Garolite G-9 is also known as electrical-grade Garolite, melamine-grade industrial laminate, phenolic, and Bakelite.

Easy-to-Machine Garolite LE Rectangular Tubes

Color: Brown
Max. Temperature: 235° F
Tensile Strength: 6,000-15,300 psi (Good)
Impact Strength: 1-1.25 ft.-lb./in. (Poor)
Hardness: Rockwell M105
For Use Outdoors: Yes

Easily turn these rectangular tubes into parts for transformers and switchgears using high-speed tooling. Made with cotton fabric reinforcement, they’re also good for crafting intricate items—from fine-tooth gears to control boards. Though easier to machine, these tubes are not as strong as those with glass cloth or paper reinforcement. Garolite LE is also called industrial laminate and phenolic.
