Hello,

i am looking for good plasticmaterial whitch is compatible with epoxy resin.

Someone nows some directions in Europe?

Thanks a lot

Does anyone know of any suppliers of edge material in north america other than snowboardmaterials.com?

They're badly backourdered and out of stock. I'm having to resort to scrounging what I can from mildly used skis I'm finding at thrift stores and ski shops.

It is a real pain in the ass to tear out the edges, clean them up, and rebend them.

Thanks for any information at all

I'm having simular issues. It's pretty diffucult having to be totally reliant on just one source for an item as important as the metal edges. I don't know at this time what it would take, but count me in on a team effort to find another source, even a European manufacturer, so that we can have a more available resource for edges. I'm not knocking SBM, I can only try to imagine how difficult it must be to try to project how many edges might sell in the next few months. And I'm sure it takes a long time to receive a shipment from Europe... manufacturing lead times, shipping via boat, customs, etc.

I'd also be interested in stainless steel and dimensionally larger edges.

Tearing edges out of old skis!!?? Man, I wish that I had some extra edges I could send you. That sounds like an awful chore.

Wishing us luck in finding another source.

I'll participate in a group order.

Any update on this? Was the group order already put in?

Or did anyone find a supplier other than SBM?

thanks

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.

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 [I think] 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.
