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

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

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

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

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.

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

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