First some info on sintered bases for those who don't know: "Sintered bases are created by taking the plastic in a powder form and slowly heating it, supercompressing it into a block, which is then sliced into sheets. The different ratings you see for bases (sintered 2000, 3000, 4000, 6000) are a rating of how dense the material is, so a sintered 6000 base is more dense than a 4000, and thus there are finer pores and the base is harder. The process of creating sintered bases allows for the bonding to create a much higher molecular weight, making it stronger than extruded. When you wax a sintered board you are filling the pores with the wax, the plastic is "absorbing" the wax like a sponge. When a sintered board goes too long without being waxed you will see it start to dry out, generally along your edges you will see the base start to turn whitish." -Taken from
My question is specifically about base density. Some manufacturers state their ski base density up front. Others I cannot seem to find no matter how hard I look. I would really like to know how the bases differ between manufacturers as this is a huge consideration for me when I buy a ski.
The following is a list of ski manufacturers and density when I can find it, would love if someone could help me fill in the holes.
Moment - Durasurf 4001
Armada - site says s7 base is their toughest base material, but doesn't say what it is.
K2 - ???
Lib-tech - NAS description says "Ultra High Molecular Weight P.E. Speed Walls" snowboard bases are "Sintered Carbon 9991 Base Material" I know my own pipe NAS seems pretty dense but it would be nice to have a real number behind it.
Atomic - ???
Rossignol - ???
Sintered Fatty Base & Edge 30% thicker (according to EVO) 30% thicker... than what it doesn't specify)
Salomon - ???
If anyone could provide info so I can fill in the holes here that would be great.
