Teflon can endure a temperature span from -80°C to +240°C for a long period of time.
The higher consistent heat Teflon is exposed to the shorter longevity. For example, exposing a Teflon-coated frying pan to high temperatures consistently for a long period of time results in exacerbation of the product and thus the slippery surface as well.
Please note that Teflon-coated tape can only endure temperatures up to 200°C, as the adhesive part of the tape is made from silicone which can only endure up to 200°C.
