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



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

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.



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
