I bought it on ebay, listing number: 301817328496

It is made by Soundcoat, the seller has a link to the product info on his listing but it is sufficiently vague. I tried burning a small sample on a flame and it is fire resistant. It melts slightly and smokes but does not burn. The surface is slightly porous. I searched for flame retardant spray but all I could find was on-line and somewhat pricey. You can concoct your own mixture by dissolving 3 parts laundry borax powder and 1 part boric acid powder in hot water and apply it with a spray mister. It may not be necessary from what I observed with the flame test. I'm not worried about resistance to fuel or oil since my engine doesn't leak. It slung water from the back of the waterpump a few years ago with the muffs but I have since replaced it and it is bone dry.
My greater concern is that it stays attached. The foam has a pretty robust adhesive backing. The spray adhesive I applied on the bare fiberglass surfaces is:

The product reviews gives it high ratings for staying put. One thing I noticed is about a 1/2" wide strip of the foam along the factory edge didn't have the self-stick adhesive applied all the way, so I added more spray where needed. I prepped the fiberglass with a wire brush & hosed it off and let it dry. After applying the adhesive and foam, I went over the whole thing heavily with a roller to make sure it was fully adhered. I try pulling an edge away and it is stuck good.
