    Leather made from Unicorn skins works best, if the Unicorn was fed only the tears of a clown during its short tragic life this makes it more heat resistant.

        If your close to a Ag Dealer Swather or Header Canvas would work,there would be moulded on cleats about every 12" but they would not bother.They should have used ones in the garbage.

            EPDM and even neoprene is not necessarily good against oils. Some may be OK, others may cause damage. EPDM is great outside in sunlight, though.

            Buna-N is quite good against oils and the like.

              Silicone baking matt.

              Reusable baking sheets are also nice dual-use item to have but maybe not for this purpose. (Glass fiber reinforced PTFE sheet.)
              Both materials are either silly expensive or very difficult to get at least in here but cheap as baking supplies.

                I bought a 12x36" piece of rubber from eBay a week or so ago for this purpose. Pretty cheap. Sold on eBay but came from Grainger.

                Edit: I am mistaken with that link. I actually bought the Buna-N. It's about the same price.

                  I got sheet rubber from Grainger. Cannot remember the part number now, but here is a sample listing,

                    ditto. only downside is that it's not smooth, so chips are a little harder to brush out of it. You can see it behind the other shields.

                      Don't forget Zoro. They are the parent and web version of Grainger. Great selection, and they are typically very inexpensive. Discounts available regularly, though usually with a min order.

                        I use welders fire blanket. It is a very thin fibreglass mat coated with rubber, very flexible light weight material. Very tough too.
                        The shortest distance between two points is a circle of infinite diameter.

                          Grainger is not nearly as expensive as they used to be.
                          They are competitive now.

                            i just bought some rubber, specialy with high resistance to oils. its epdm. so i guess there are different formulations.

                              EPDM is a specific material, and it is very doubtful that there are many varieties. Observe this datasheet, which specifically says: "Not recommended for oils, gasoline, kerosene, aromatic and aliphatic hydrocarbon, halogenated solvents,concentrated acids, non-polar solvents, petroleum oils and aromatic fuels."

                              https://www.marcorubber.com/download...heet-E1121.pdf

                              Now, I do not know if there are MIXES of materials including EPDM, or multi-layer materials made for some reason.

                              But there is pretty good reason to believe that the EPDM rubber is not good with oils etc. Not sure of the problems, it may simply swell up and become weaker, that is a typical response of some materials.

                              Another source:

                              https://satoriseal.com/epdm-rubber/

                              Here is yet another reference, indicating "severe effect" of diesel, kerosene, grease, petroleum hydraulic oil, even olive oil.

                                i humbly admit having mixed up epdm and nbr. (todays world seems to mostly consist of capital letter combinations.)
