not same material as snow board :
snow boards scratches easy, and, the material is porous, so that the wax can stick on it ( and that's why you need to wax it, because it's porous ( by the way, if someone can explain me why they dont do slik surfaces with no need to wax on snowboards, he's welcome )).
cut boards ( and the plates on glows ) dont scratch easy ( you cut on it and it does not event show wear ) and there are made of non porous material ( because they are food grade, they can't be porous ).
maybe a thin slice of such a board could be laminated as bottom sheet of a board ??
You're wrong, the material used on most snowboard bases is UHMW PE. (ultra high molecular weight polyethylene).
from : http://beansnowboarding.com/boards/deck-tech/
"Our base material is made of UHMWPE. That monstrous acronym stands for Ultra High Molecular Weight Polyethylene, and basically means each little plastic molecule in this stuff is stronger and hard wearing than most other plastics on the planet. UHMWPE is standard base material in the snowboard industry, and the only big difference is whether it’s sintered or extruded. Extrusion is the cheap way to go and was probably used on your little sister’s My Little Pony snowboard that she won at the mall. Bean Snowboards only uses sintered base material, and the sintering process (melting lots of microscopic plastic pellets together to make one big piece) makes little pores in the plastic that hold wax to keep you riding fast for a long time between waxes."
A cutting board is made from HDPE (high density polyethylene) or HMWPE (high molecular weight polyethylene).
Both are not great for base materials in my opinion because they are difficult to bond and impossible to repair well.
