High-temperature insulation tapes include KAPTON high-temperature tape; Teflon high-temperature tape; high-temperature masking tape; PET green high-temperature tape; high-temperature double-sided tape, etc.
Identification of true and false high temperature tape:
High temperature resistant insulating tape is mainly composed of two parts: base material and glue.
Some manufacturers have adopted a method to reduce costs and prices. The real quality is greatly compromised. Taking KAPTON high temperature tape as an example, the fake one is far lower than the real polyimide in terms of temperature resistance and insulation performance. Amine tape. The base material it actually uses is a brown PET film coated with silica gel. Because the temperature used in some industries does not need to be too high, not exceeding 260 degrees, the maximum temperature resistance of PET is 220 degrees, so it is generally Under the circumstances, it is not easy to find out. What‘s more, the temperature resistance of using other glues that are originally silica gel water is far less than 150°.
PET Tape:
Mainly identify from the following points: 1. Taste; 2. Appearance; 3. Residues after ignition;
The actual high temperature test, after the high temperature of 260 °, check whether there is residual glue, shrinkage and other phenomena.
