[0002] Heat-resistant tape is a special type of tape that can maintain its adhesiveness and physical properties in high-temperature environments and will not soften, melt or lose its adhesiveness due to high temperatures. Heat-resistant tape is usually made of a high-temperature resistant base material and adhesive and is suitable for applications that need to withstand higher temperatures.

[0003] Heat-resistant tape is mainly composed of a base material and an adhesive. During the use of heat-resistant tape, due to the generally high temperature of the use environment, the edge of the tape is most susceptible to external factors and embedded with dust, causing the edge of the tape to warp up and unable to adhere tightly, increasing the possibility of falling off and affecting the normal service life of the tape.
