Do you really know how to purchase the good kapton tape?

Nowadays, With the increasing demand for high temperature tape, many Factories move into this filed and provide different quality kapton tape.

Do you want to know how to purchase the good quality and avoid the poor? Today I will introduce you few ways to distinguish it.

1. Checking the material and test with temperature

For fake kapton tape, the backing is PET Film, the highest temperature resist is 220 degree . But for polyimide film , the highest temperature can be 280 degree. After through the temperature of 260degree, if there is residue/shrink problem, It’s fake.

2. Smelling

If the smelling is strong and with a sour odor, It’s probably a bad one.And the Viscosity and retention is not good.

3. Appearance --Checking the brightness of the tape

Generally speaking, if same thickness, the more darker one is the bad one,The fracture is very high and the strength is poor 

4. Checking the residue after burning

You can bake it with a lighter for 1 to 2 seconds and then touch it with your hands. If there is glue on hand, it’s the bad one.

5. There is other bad phenomenon on the market you need to notice.

For example, using thick core in order to looks big ,but the actual length is shorter than they said. Or using the unqualified glue, though with good initial viscosity but cannot last for long time.
