Useful high temperature material
Don't know the name for it, used in "oven tray liner". Takes high
temperature, does not stretch or tear and is only 0.05mm thick, highly flexible. Under a microscope it appears to be woven kevlar fibres squashed between PTFE sheet. Unfortunately even puncturing with hundreds of needle holes I cannot find a way of gluing it, even just a lap joint with no forces involved, tension or shear. probably same as this http://www.theptfeshop.com/product.p...ing-tray-liner Found in local ordinary baking products shop, quite cheap |

So, if you want to attach it, you're limited to stapling, stitching, clamping... Safety pins will work, too. |

Much of the "non-stick" baking stuff is silicone these days. -- Jim Yanik jyanik at localnet dot com |

If you've ever heard the sound of kevlar sails rattling in use on a modern racing yacht , it is that sound if you tap the material, a metalic sort of sound. Latest marginal gluing attempt is epoxy after grinding back the ptfe covering, will see tomorrow, if any sort of adhesion. |

So lightly grind back the very thin ptfe coating with a Dremmel disc, on to be joined faces |
Useful high temperature material
wrt last
peel strength , not shear strength |
Useful high temperature material
It easily forms into a cylinder of 3mm radius and can go tighter without
