What type of tape is made to be used in extreme heat (very high temperatures)?

I'm looking for a very special kind of tape that I can use to hold down a heating resistance chain. The dang Mica that was holding everything together tore, and when I tried to fix it, it just got pulverized into tiny bits and pieces instead. Every time I was trying to insert literally anything that could just barely pierce a tiny hole into it so that I can keep the resistance chain together, the dang thing would just fall apart faster than a wet paper. Although I understand the advantages of using Mica (as it is non-combustible, an insulator as well as a dielectric), I really don't like it. It's giving me a headache and it is extremely sensitive for whatever reason. Any suggestions would be greatly appreciated.
