Basalt Tapes

Basalt, a volcanic rock, is spun into fibers and assembled as yarns that are expertly woven into high temperature basalt tape. These environmentally friendly and 100% recyclable woven basalt tapes, available in plain and twill weaves, take advantage of the strength, flexibility, and excellent thermal properties inherent to basalt fibers.

Our basalt tapes provide enhanced heat resistance, high thermal performance, and impressive durability. Basalt tape is a more durable material than fiberglass or carbon fiber tape and works as an excellent heat shield at continuous operating temperatures of 1382°F (750°C). When applied as an exhaust heat wrap, this tape provides thermal insulation that increases the efficiency of exhaust systems and reduces radiant heat to surrounding components and passengers of cars, trucks, and motorcycles. Basalt tapes can be coated in vermiculite or treated with pressure sensitive adhesive to aid in installation.
