Multipurpose Flame-Retardant
Garolite G-10/FR4 Tubes

A good all-around choice, Garolite G-10/FR4 is strong, machinable, and electrically insulating. It meets UL 94V0 for flame retardance.

Multipurpose Flame-Retardant
Garolite G-10/FR4 Discs

Multipurpose Flame-Retardant Garolite G-10/FR4 Discs

A good all-around choice, Garolite G-10/FR4 is strong, machinable, and electrically insulating. It meets UL 94V0 for flame retardance.

High-Temperature Garolite G-11 Rods

Offering higher strength and better heat resistance than Garolite G-10/FR4, Garolite G-11 is suitable for continuous use in elevated temperatures.

Halogen-Free Garolite G-10 Rods

Use Garolite G-10 in place of Garolite G-10/FR4 for applications that are sensitive to halogen, such as in nuclear plants. It's strong, machinable, and electrically insulating.

Halogen-Free Garolite G-10 Tubes

Use Garolite G-10 in place of Garolite G-10/FR4 for applications that are sensitive to halogen, such as in nuclear plants. It's strong, machinable, and electrically insulating.

Ultra-High-Temperature
Arc-Resistant Garolite G-7 Rods

Choose these Garolite G-7 rods for their high heat tolerance—they withstand temperatures up to 425° F. While not as strong as Garolite G-9, they offer better arc resistance in dry environments.

Ultra-High-Temperature
Impact-Resistant Garolite Tubes

Used in turbine bearings, downpipe gaskets, and other machinery, these Garolite tubes withstand heavy impacts and temperatures as high as 500° F.

Arc-Resistant Garolite G-9 Rods

Frequently called electrical-grade Garolite, this Garolite G-9 is strong, electrically insulating, and arc resistant in dry environments.

Composite Material Selector Packs

Composite Material Selector Packs

Each pack includes one 2" circle of GPO3 fiberglass and Garolite XX, XXX, CE, LE, G-3, G-7, G-9, G-10, and G-11.

Fiberglass

Arc-Resistant GPO3 Fiberglass Rods
