Six ways to identify true and false Kapton heat resistant tape

Article source: KYD Electronic CO., Ltd / Author: KYD Electronic CO., Ltd / Publication time: 2022-07-06

High temperature resistant tape, also known as Kapton tape or polyimide tape, the tape is based on polyimide film, coated with high-performance silicone pressure-sensitive adhesive on one side, and has single-sided fluoroplastic release material compounded or not compounded Two types of materials. The coating precision reaches ±2.5um, no scratches, wire drawing, etc., good shearing, easy punching die-cutting, excellent high temperature resistance and solvent resistance. Gold finger tape storage conditions are 10-30 ℃, relative humidity 40-70%; avoid direct sunlight and high temperature (above 40 ℃) high humidity (75% RH) environment.

Six ways to identify true and false Kapton heat resistant tape.

1. Look at the material

Kapton heat resistant tape is mainly composed of substrate and glue. If it is a fake Kapton heat resistant tape, its temperature resistance and insulation performance are far lower than the real Kapton heat resistant tape.

2. Smell

If the Kapton heat resistant tape has a strong smell and is accompanied by a sour smell, then the Kapton heat resistant tape is likely to be fake, and its stickiness and retention will be very poor.

3. Carry out high temperature test

Carry out the actual high temperature test on Kapton heat resistant tape. After the high temperature, check the peeling force, whether there is residual glue, shrinkage and other phenomena. Because the temperature resistance of real Kapton heat resistant tape is usually between 120 degrees and 260 degrees.

4. Look at the appearance

Looking at the brightness of the Kapton heat resistant tape surface, generally speaking, the color of the inferior high temperature tape is a little dark, and the probability of breakage is very high, and the strength is poor. On the contrary, good quality Kapton heat resistant tape has better surface gloss.

5. Look at the residue after burning

You can bake it with a lighter for 1 to 2 seconds before touching it with your hands. If it is ordinary, the glue will stick to your hands after burning, but if it is real Kapton heat resistant tape, there will be no glue sticking to your hands.

6. Carry out material inspection

When testing, see the instructions for Kapton heat resistant tape. Because of the different types, some Kapton heat resistant tapes have the same strong stickiness after high temperature resistance, some are torn off without leaving adhesive residue after high temperature resistance, and some are not deformed after high temperature resistance, so it depends on the specifics. How is your tape.
