High-temperature adhesive tapes are used in the electronics industry, and the high-temperature resistance is usually between 120° and 260°, and is usually used for painting, lacquered leather processing, painting masking and fixing electronic parts in the manufacturing process, printed circuit boards and high-temperature treatment masking and other work. The types of high-temperature tapes include Teflon high-temperature tapes; high-temperature masking tape; PET green high temperature tape; There are many types of high-temperature double-sided tape.
Identification of true and false high-temperature tapes: high-temperature tapes are mainly composed of 2 parts, substrate and glue 2 parts, some manufacturers in order to reduce costs, but also to reduce the price of a method, its real quality is greatly reduced; Both the temperature resistance and insulation properties of the fake ones are much lower than the real polyimide tapes.
The actual substrate of the high-temperature tape is a brown PET film, coated with silicone, because the actual application temperature of some industries does not need to be too high, not more than 260 degrees, the maximum temperature resistance of PET is 220 °, so it is not easy to find under normal circumstances, and even more, the use of other glues that are originally silica gel water, its temperature resistance is far less than 150 °.
The identification of high-temperature tape is divided into the following points: first, smell the taste; Second, look at the appearance; 3. Residue after combustion; Fourth, carry out the actual high temperature test, more than 260 degrees, to see if there is any residual glue, shrinkage.
