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.
