There are many different types of double sided tape in the repair industry, from more than just TESA, 3M also has some good stuff according to other techs.
All about... double Sided Tape
If you know other good tape models that have verify-able origins and have data sheets, contact me and let me know!
If you're tape maker and you come across this page, come find me and give me tape to test!
Have a look at the following overview of each model of tape mentioned to get a quick overview in your head of its usage before proceeding further.

General Specifications
- The following tables show technical data that is freely available on the manufacturer's website and is not some sort of special access stuff.
All Iv done is put it together for the repair industry to look at in an easier to digest way.

Adhesion Properties
- When you are deciding on which tape to use, its always best to focus on the harder to adhere to material.
- Pay attention to the thermal limits of the adhesive at the bottom of the list. A hot car can get awful close to 51970s breakdown point....

Hi! I was informing myself as I plan to repair my own phone. At a certain point, I wondered which tape I would need. Luckily I stumbled on your video. However, in the repair process, do you prefer the tape to fail on the base of the phone, or on the glass screen, when prying it open? I did seem to miss this bit of information.
I can imagine this to be an important aspect in the repair process. Thank you for your time. G
