Following the theory that heat accelerated key failure a switch to a different material would make sense if its melting point was higher. Some quick googling indicates nylon has high temperature resistance.

Followed this tutorial and fixed my broken T100. I had not replaced a digitizer before and spent about 2 hours. I used iFixit’s magnetic mat to keep all the screws organized, which was essential since there were three types of screws. I struggled with the last step to figure out the proper technique to separate the two (how much heat to apply and how to leverage the parts apart), but got through it in the end. Thanks!
