Hi, i just have a simple question, is the hdpe the same as uhmwep?
And how wide should be the layer for the correct flexion?
Thanks.
HDPE vs UHMWEP

Yes I believe so, hdpe=high density polyethylene, uhmwpe = ultra high molecular wheight polyethylene. Pretty much the same thing.
what was that last question? Are you talking about thickness? standard bases are 1,2-1,5 mm thick. The thickness of the base don't affect on the total stiffness. (the core does)

They're similar but not exactly the same. In UHMWPE the polymer chains are significantly longer than in HDPE. Since plastics are a little more variable manufacturer than say alloys with specific proportions of metals, which have standards, I'm not sure how different UHMWPE and HDPE actually are, and I couldn't quickly find a great reference.
But generally UHMW and HD have similar tensile strengths, but UHMW has much higher impact resistance and is actually slightly lighter since the longer chains force a less "crystaline" structure. Well that's what wikipedia said.
I think either would work fine for sidewalls or tip spacers.
