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.

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)

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.
