6mm Sintra

This 8x12 inch, 6mm thick expanded PVC sheet is extra thick for substantial stiffness. It's smooth and easy-to-form with a knife, it glues very easily with super-glue and epoxy.

The black-coloured sintra absorbs heat very well, and BEAMbots built with it have been known to "melt down" a bit when put under strong lamps!
