High temperature resistant tape is the adhesive tape used in high temperature working environment. It is mainly used in electronic industry. The temperature resistance of high temperature resistant tape is usually between 120 ℃ and 260 ℃. The high temperature resistant tape is commonly used for painting, baking leather processing, coating shielding, fixing in the process of electronic parts manufacturing, printed circuit board and high temperature treatment shielding. High temperature tape includes Teflon high temperature tape, high temperature textured paper tape, pet green high temperature tape, high temperature double-sided tape, etc.
Identification of genuine and fake high-temperature tape: the high-temperature adhesive tape mainly consists of two parts: base material and glue. Some manufacturers adopt a method to reduce the cost and price, and the real quality is greatly discounted. Whether the thermal resistance or insulation performance of the fake tape is far lower than the true one, the actual substrate is made of brown PET film coated with silica gel, Because the temperature of some industries does not need to be too high, not more than 260 degrees, the maximum temperature resistance of pet is 220 degrees, so it is not easy to detect in general. What's more, the temperature resistance of using other glue instead of silicon glue is far less than 150 degrees.
The authenticity of high temperature resistant adhesive tape is mainly identified from the following points: 1. Taste; 2. Appearance; 3. Residue after ignition and combustion; 4. Actual high temperature test, check whether there is residual glue, shrinkage and other phenomena after 260 ° high temperature test.
