They make a batting for that. It's called Wrap-n-Zap by Pellon. My local JAF sells it. Even with that special batting, Pellon recommends only heating it for 2 minutes at a time, for a maximum of 8 minutes.

You definitely don't want to use the Insul-Brite. It has metal in it & can spark in the microwave, causing a fire.
Theoretically, you can use any 100% cotton batting -- like Warm & Plush or Warm100 -- although The Warm Companies says that none of their products are designed to go in the microwave. I assume that's for liability reasons, as many people do not read or else just plain ignore safety instructions about how long something can actually be in the microwave. If you leave any cotton in the microwave for too long, eventually it will get overheated & catch fire (that's fabric & batting).
