Would be surprised if LDPE is the more shatter prone. Why would lower density be more brittle, surely it'd be even softer and more malleable than a high density variant?

Those chopping boards you used on Tormenta 1 were LDPE, need I say more? ;-) LDPE has shorter polymer chains and as a result breaks more easily as there are less crosses and linkages. (I hope I remembered that right)

I don't think they were LDPE. There seems to be two kinds of off the shelf chopping board, the horribly brittle type (literally like glass) I had and the slightly gummy type. I have cracked the latter in tests also. It's very much like a cracky HDPE.

The glassy stuff I had was inconsistently moulded with holes inside, was semi opaque and was much more like acrylic or polypropylene than any polyethylene I've messed with.

In any case I'm fighting Niels twice so hopefully it is a slightly cracky type.
