The fiberglass ropes are made of continuous filament texturized yarns and are extremely strong, resilient, and flexible. They are widely used as gasket for industrial ovens and furnaces, boilers and wood burning stoves. They are asbestos free, cause no harm to health, making them ideal replacements to asbestos ones. For higher loads, the round braided and square braided ropes can be reinforced by steel wires. They also can be coated with graphite or vermiculite to increase thermal insulation and abrasive resistance.
