The G-7 Silicone Glass Rods are designed for high-performance in demanding environments. Made from a robust combination of glass fibers and silicone resin, they provide excellent electrical insulation, mechanical strength, and heat resistance. With a maximum operating temperature of 180°C, these rods maintain their structural integrity even under high-stress conditions, making them reliable for long-term industrial use.
