To distinguish the authenticity of PI (polyimide) high-temperature resistant tape, a comprehensive judgment can be made from the following aspects:

1、 Observe the appearance and material

Color and Gloss: Genuine PI high-temperature resistant tape usually has good gloss and uniform color, with a smooth and flawless surface. Counterfeit tape may have dark colors, poor glossiness, or surface defects such as unevenness and bubbles.

Substrate thickness: The substrate of PI tape is usually thin but tough, and can be preliminarily judged by measuring its thickness. If the substrate is too thick or too thin, it may not be a genuine PI tape.

2、 Smell the scent

The materials used in the production process of genuine PI high-temperature resistant tape are relatively environmentally friendly and usually do not have a pungent odor. Counterfeit tape may use inferior materials or additives, which can emit a pungent odor.

3、 Ignition and combustion test

Residual form: Ignite a small piece of tape with a lighter and observe the residue after combustion. The residue of real PI tape after combustion is usually in powder form and does not produce obvious black smoke or odor. And the residue of counterfeit tape after burning may gather together or produce a large amount of black smoke and odor.

Burning process: True PI tape has a relatively stable flame and is not easily dripped during the burning process. Fake tape may burn rapidly, have unstable flames, and even drip combustibles.

4、 Actual high temperature test

Temperature resistance: Place the tape in a high temperature environment (such as above 260 ° C) and observe whether it deforms, remains adhesive, or shrinks. True PI high-temperature resistant tape should be able to maintain stable performance at high temperatures without obvious deformation or residue.

Testing time: In order to more accurately evaluate the temperature resistance of the tape, a long-term high-temperature test can be conducted. For example, place the tape in a high-temperature environment for several hours or days and observe its performance changes.

5、 Check labeling and packaging

Identification information: Genuine PI high-temperature resistant tape usually indicates product name, specifications, manufacturer, production date, and other information on the packaging. You can preliminarily determine the authenticity of the tape by checking these identification information.

Packaging quality: Genuine PI tape usually uses high-quality packaging materials, with tight and undamaged packaging. Counterfeit tape may have simple packaging and be easily damaged.
