1roll of Sublimation Heat Resistant High Temperature Transfer Electronics Masking Welding PCB Protection Vinyl Tape 13mmx33

does it work to protect from burning yourself on hot wires?

A roll of this was included in my heat press machine, but what is it for? I've made some shirts already. It didn't involve this tape.

can this be used on oven racks? My oven racks do not fit as the side walls have bowed. Is it food safe?

How thick is the tape?
