Without going into to many details, I'm in need of a lightweight material that can act as a flame shield. Said material needs to be lightweight because the application is for a handheld device. I'm looking at a couple square feet of material. It will need to withstand a direct propane flame (my guess is 700-800 degF, haven't done temperature measurements on this burner) for upwards of a half hour at a time. Is there any sort of fabric that can withstand that sort of situation. I imagine even though kevlar is fire resistant, it will start to break down after significant duration. Is there any sort of metal-strand fabric that might work for my application. Or is my best bet going to be just to stick with a solid metal plate?
