Because the glue is only part of the tape. Green tape carries it on PET polyester film. Amber tape carries it on polyimide film. Change the film—or the exact adhesive recipe—and the finished tape can behave differently.
Start with the job, not the colour: what surface, which production step, how hot, and for how long?
Two tapes can feel sticky in your hand and still belong in different production conversations. The finished construction—not one ingredient by itself—is what you test.
For coating, plating or other temporary masking, start by checking the actual part and the full heat cycle. Do not choose it just because the tape is green.

It is commonly considered for PCB masking and demanding heat steps, but the real surface, process and removal result still decide whether it fits.
See the polyimide tape data →The adhesive is like the zipper: it helps the tape hold on. The carrier film is like the fabric around it. You would not choose a winter coat only by checking the zipper. In the same way, do not choose a high-temperature tape by adhesive name alone.
These four details let us rule out poor matches before you spend time testing them.
Metal, PCB, glass, coating or another surface? Adhesion and removal can change with the surface.
Powder coating, plating, soldering or another step? The process around the tape matters.
Use the temperature of the real part or process—not only the oven set point when they differ.
Minutes, an hour, or repeated passes? Temperature without time is only half an answer.
You do not need to read everything. Start with the scene that matches your work, then check the product data behind it.

No. They may belong to the same adhesive family, but the exact formulations can vary and the carrier films are different.
No. Colour is a visual clue, not a complete selection rule. Check the construction, process, temperature, time and actual peel result.
Not responsibly. Add the surface, production step and heating time, then validate the sample on the real part.
Each link below answers a different next question: product construction, application scene or more short video guidance.
Show us the surface, where the tape sits in your process, the maximum temperature and how long the heat lasts. We can then narrow the sample options before you test them on the real part.
