how to identify high-temperature tape, high temperature resistant tape is under high temperature and the working environment to use adhesive tape. Is mainly used in the electronics industry USES, high temperature heat-resistant pressure-sensitive adhesive tapes and heat-resistant performance is usually between 120 to 260 degrees, high temperature resistant adhesive tape used to spray paint, leather processing, coating covered and electronic parts of the lacquer that bake process in the fixed cover, printed circuit boards and heat treatment. High temperature tape high temperature including KAPTON tape; Teflon high temperature adhesive tape; High temperature textured paper tape, PET green high temperature adhesive tape; High temperature tape, etc.

true and false identification of a high temperature adhesive tape, high temperature adhesive tape is mainly consists of 2 parts base material and glue 2 parts, parts manufacturers to reduce costs, is also a way to lower the price of, its real quality at a discount greatly; KAPTON high-temperature tape, for example, false heat resistance performance and insulation performance are far lower than the real polyimide tape, it actually is the dark brown's PET film base material used, coating of silica gel, because the temperature of the practical application of some industry does not need too high, no more than 260 degrees, the highest heat resistance is 220 ° of PET, so in general is not easy to find, what's more, using as a silica gel water and use other glue, its temperature resistance is far less than 150 °.

high temperature heat-resistant pressure-sensitive adhesive tapes to identify true and false mainly from the following points: 1. Taste; 2. Appearance; 3. After burning residue; 4. Actual high temperature test, the high temperature of 260 °, check whether there is residual glue, the phenomenon such as shrinkage.
