SparkFun PRT-10687 High Temperature Adhesive Tape – (1cm, 33m)
This is a 33 meter roll of polyimide tape. This tape is a fantastic insulator, like electrical tape, but it can withstand temperatures as high as 258°C (496°F). It also provides good resistance to corrosion and the silicone adhesive holds tight throughout the tape’s rated temperature range. This is a good choice for insulating components inside of an enclosure that might be subjected to extreme conditions.
