    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.
