Heat Resistance Basalt Tape is constructed from fragmentized lava rock that is extruded into fibers to create a heat wrap that will give you strength and performance you expect from an exhaust header wrap. When properly installed, the proprietary weave in our heat wrap will allow an even dissipation of heat so that it will not over insulate your pipings or create any hot spots. Promotes increased flow and keeps down the under the hood temperatures for improved performance and reduced vibration breakdown. Chemical, fire, acid and oil resistant that will not shrink or loose flexibility under extreme conditions. This Heat Wrap is very easy to install and tightens down onto pipings without needing to be wet. Is extensively used in the wrapping of exhaust bends or other exhaust parts. Can easily cut with a scissors. Resistant to a continuous temperature of 650°C, peak temp at 1096°C. Melts at 1319°C.
