What Ski Brands Integrate Urethane into Sidewalls?
I know k2 use to do this, just wondering if other ski brands do this.

UHMW (which is what Praxis, ON3P, Moment, and others use for sidewalls) is polyethylene. ABS is the other common material used, which is also not urethane.

I remember a few years back, I broke sidewalls on two pairs of Head IM88's. For the 3rd year of the ski, they switched to an ABS composite material, which had random very small fibers to strengthen the already strong ABS. Very tough sidewalls.

Liberty got the urethane- not sure in all there stuff. Its allot more expensive material and machines to do this so chinese made mostly you will see this or very small boutique skis. The euros dont get into this much. Its not that the urethane is "tougher" per se, it bonds extremely well and flexes very well at cold temps. All abs is not the same and urethane is just as complex chemistry.

Urethane is weak and brittle. No good for side walls. P-tex is better.

Urethane as a material is pretty flexible and resilient. But when urethane was widely used in sidewalls in the past, they often literally cracked and fall out in chunks whenever you impacted anything hard like a rock or stump.
P-tex is better. Most modern skis use it.Leave No Turn Unstoned!

So that everyone reading this is clear, p-tex and UHMW are the same thing.

I was confusing ABS with Urethane.

Yeah ur totally wrong urethane is one of the most teprature stable, abrasion resistant, flexible and durable materials known to man.
Its great for all types of stuff.
Uhmw is the industry standard because its cheap and easy to finish and produced globally.
Polyether based urethanes are complex, harder to finish and require more complex machinery not already integrated into the ski industry.
Lots of companies are useing abs as well still. Not all abs is the same. The first chemical makeups of abs used were brittle in the cold. Not the case any more.
The uae factory makes some of the finest fit and finish water skis, snow skis and snowboards in the world and they use allot of abs in there products.

When I mean integrate Urethane into sidewalls, I do not mean using Urethane the entire length of the sidewall. Most companies that used urethane integrate the urethane betwwen p-tex or ABS. I find that an ABS/urethane sidewall makes for a very smooth, damp feeling ski. Especially on edge.

Not sure. K2 use to do this with their Absorb sidewalls. They would use Urethane inbetween ABS as well as under foot.
I wish I had the money to design and press my own skis because I think Urethane used in the right places really maximizes dampening, and reduces chatter, without making the ski's lose agility and feel.
I really don't know any other companies that use urethane, maybe it's too expensive.

They list something called "durathane" where a manufacturer would typically put VDS. Everyone advertises that it's for dampening, but it's more for bonding and preventing delaminating more than anything else. I'm sure it's typical voodoo BS. Like Liberty being the only one that uses bamboo.Training for Alpental

You're right and wrong. VDS is for bonding. It also has the biggest effect on damping(not dampening) than any other part of the laminate, followed by the plastics(base, topsheet and epoxy).
