    High-Temperature Garolite G-11 Sheets and Bars

    Offering higher strength and better heat resistance than Garolite G-10/FR4, these Garolite G-11 sheets and bars are suitable for continuous use in elevated temperatures. They retain at least 50% of their structural strength at temperatures above 300° F. Made of an epoxy resin with fiberglass fabric reinforcement, Garolite G-11 is sometimes called epoxy-grade industrial laminate and phenolic.

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

    Image of Product. Front orientation. Garolite. 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.

    Electrically Insulating Garolite XXX

    Image of Product. Front orientation. Garolite. Electrically Insulating Garolite XXX.
    More electrically insulating than Garolite XX, these tubes are often machined into insulating washers, bushings, transformer spacers, and parts of terminal boards. Made of phenolic resin with paper reinforcement, they’re lightweight yet strong. While not as strong as Garolite XX, they absorb less water, so they work well in humid environments. These tubes won’t split during machining. They also won’t wear down tooling as fast as phenolic products with glass cloth reinforcement.
