UHMW Polyethylene
Sand Slurry Test

For Plastic Skis, Steel Skis and Ski Skins

Each material listed below was rotated 24 hours @ 1750 r.p.m. in a 50/50 sand/water slurry.  The weight loss for each of the materials is relative to100 and so...

The lower the number... the better the abrasion resistance.

This shows that UHMW (Ski Savers) outwears High MW 3:1

Plastic does slide great on snow. But, when direct pressure is applied, it cannot hold up.

The plastic cubes would have floated in the water/sand mix, and compressed on impact. The steel cube would have slammed against the walls of the container. Allowing the granules of sand to chip away at it's mass. Take a hacksaw to a steel ski and a plastic ski, if this does not make sense to you. I did it for you.
