Arc-Resistant Garolite G-9 Angles

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.

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

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.
