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

Found in local ordinary baking products shop, quite cheap

If you're attaching to another plastic material, use your HOT air soldering tool.. known as "Plastic Welding"

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

aren't those -silicone- baking sheets? Much of the "non-stick" baking stuff is silicone these days.

One company I worked for used a product they referred to as 'kapton tape'. High temp (withstood soldering irons) and adhesive backed.

Of course, your def. of 'high temp' might differ from theirs.

Nothing rubber about this material. 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.

tap

shear strength of a test of 12 x 6mm plain lap about 1kg , more than required for current use, high temp ability not required this time. So lightly grind back the very thin ptfe coating with a Dremmel disc, on to be joined faces

peel strength , not shear strength

It easily forms into a cylinder of 3mm radius and can go tighter without cockling
