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

    Image of Product. Front orientation. Garolite. 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 rods, they offer better arc resistance in dry environments and a higher level of electrical insulation. These rods are constructed of a silicone resin with fiberglass fabric reinforcement. Garolite G-7 is sometimes called silicone-grade laminate, phenolic, and Bakelite. Use it to fabricate high-frequency telecommunication equipment and parts that require a high tolerance to heat.

    Ultra-High-Temperature Arc-Resistant Garolite G-7 Sheets and Bars

    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. They are constructed of a silicone resin with fiberglass fabric reinforcement. Garolite G-7 is sometimes called silicone-grade laminate, phenolic, and Bakelite. Use it to fabricate high-frequency telecommunication equipment, transformers, and other parts that require a high heat tolerance.
