Hi jk, as it's a PVC it should survive, but will be very soft. We have used Mylar in transformers for decades (Mylar is old stuff). For high T we use Kapton instead. see: http://www.nitto.com/product/manufacture/spv224-214.htm http://www.nitto.com/product/manufacture/ip03-2.html If you need closer data I have friends who know a lot about Mylar. Why not send DENKA a q?

Does anyone know what is the blue mylar tape (Nitto tape spv 224) maximum operating temperature? Can it survive for 125 C for extended time (few hours)? I have difficulty to find the data sheet on line. Many thanks.
