About Composites

Multipurpose Flame-Retardant Garolite G-10/FR4 Rods

A good all-around choice, Garolite G-10/FR4 is strong, machinable, and electrically insulating. It meets UL 94 V-0 for flame retardance.

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 94 V-0 for flame retardance.

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 94 V-0 for flame retardance.

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.

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.

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.

Flame-Retardant High-Temperature
Garolite G-11/FR5 Tubes

A flame-retardant version of Garolite G-11, these tubes are commonly used to make bushings, standoffs, and spacers for areas with high temperatures. All are stronger and resist heat better than Garolite G-10/FR4.

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.

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-Low-Temperature Garolite G-10 CR Tubes

Rated for temperatures down to -450° F, this Garolite G-10 CR performs better in cryogenic applications than other glass epoxies.

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.

Fiberglass

Structural FRP Fiberglass Rods

An alternative to wood in structural applications, FRP fiberglass is strong and lightweight.

Structural FRP Fiberglass Round Tubes

An alternative to wood in structural applications, FRP fiberglass is strong and lightweight.

Arc-Resistant GPO3 Fiberglass Rods

Offering excellent arc and track resistance, this GPO3 fiberglass is often used for electrical applications in humid environments.

Arc-Resistant GPO3 Fiberglass Round Tubes

Use these round GPO3 fiberglass tubes for electrical applications in humid environments.

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.

Rebar

Reduce the chance your concrete will crack from expansion and contraction and other tensile stresses.
