This listing has been featured as a Tech of the Week 
This alkoxide treatment process from DuPont strengthens mica paper and makes it suitable for use as a flexible, inexpensive roll-to-roll substrate able to withstand much higher temperatures than polymer substrates can reach -- 600¶C to 700¶C. Water-resistant mica papers containing vermiculite or muscovite can be laser-cut and scribed easily like a polymer.
