Polyimide tape (often sold as “Kapton®” by Dupont) has some amazing properties. It’s heat-resistant, very tough, stretches very little, and has this wicked amber-brown translucency. We often use it to tape sensors to circuit-boards when we run them through the oven (measuring oven temperatures).

• Resists temperature extremes from -73°C to 260°C (-100°F to 500°F).
• Won’t soften at higher temperatures.
• Flame, chemical and radiation resistant.
• Backed with a silicone adhesive.
