Get a clear view of your materials through this transparent rubber. Sheets are covered with a protective clear film (remove film before using). Rubber has a temperature range of -80° to +425° F. "
That was straight from the spec sheet of a supplier. It is not impossible to find and goes for about $12.00 per square foot at 1mm thickness. That will get you 24 gaskets at 2" X 3" so I don't see it being a huge cost but rather a cost saver. If you get it adhesive backed, it's a couple dollars more per square foot.

Sounds interesting. Thats about $.50 a block which is pretty close to the same as a custom order O ring. I would prefer it ot be non adhesive as I try to make all my blocks cleanable.
