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

Graphite is added to this Garolite CE to provide a slippery surface that reduces friction and makes this material conductive.

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

Often used for terminal boards, electrical housings, end plates, and structural components in high temperatures, these sheets are a flame-retardant version of Garolite G-11. All are stronger and resist heat better than Garolite G-10/FR4.

Garolite G-7 withstands temperatures up to 425° F—higher than any other grade of Garolite. While not as strong as Garolite G-9 sheets, these sheets and bars offer better arc resistance in dry environments and a higher level of electrical insulation.

Rated for temperatures down to -415° F, this Garolite G-10 CR performs better in cryogenic applications than other glass epoxies.

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

Made with a flame-retardant resin, this FRP fiberglass meets ASTM E84 Class A.

SG-200 fiberglass withstands temperatures up to 410° F—higher than any of our other fiberglass raw materials. It’s also stronger than FRP fiberglass and easy to machine.

Hard fiber is the easiest composite to machine, making it good for creating custom parts. Also known as vulcanized fiber.
