Heat-resistant and pressure-sensitive adhesive tape, also known as fixed adhesive tape, is a kind of adhesive tape formed by coating special adhesives on the basis of glass fiber tape. It has wide bandwidth, thick thickness and the highest temperature resistance. In electric heat tracing system, after installation, the heat-resistant pressure sensitive belt is used to fix the electric heat along the radial direction of the pipeline, and its length depends on the length of the heat tracing pipeline.
