UHMW (Ultra High Molecular Weight Polyethylene) Sheet, Opaque White, Standard Tolerance, ASTM D4020, 1" Thickness, 12" Width, 12" Length

Worked well for my needs.

This 12" x 12" sheet came with slick surfaces front and back. (I don't care, but wanted to mention it for anyone expecting a matte or textured surface.) This is very tough material. Before I started my project (linkage guard for off-road motorcycle/high-impact application), I took it out back and put it on top of a cinder block, then used a hammer to attempt to break off a 1" corner section. It didn't flinch at all, and mind you this is only 1/4" thick. It did eventually bend a little after repeated pounding but no sign of cracking, splintering or breakage. When I tried to cut it with a hack saw, it fought me hard. I'll have to borrow my buddy's band saw to get the cuts I need without pulling a muscle.

good

Cut up the 12x12 sheet to make a board and ski mount for my snowbike. The material is extremely dense and was hard to sand on a belt sander, so that speaks to its durability. I also dropped the bike in my garage and it landed right on both wedged pieces of plastic and it didn't even scratch it. Has held up to a full day of whoops and riding with a pow surf attached and nothing happened to it at all. Very happy with this purchase.

Used it to make a dash console with cut outs for switches and gauges for my boat. Cuts cleanly, holds a wood screw, strong enough to bolt on, weather resistant. Perfect.

For those who don't know, longboarding can involve speeds in excess of 35 MPH. Speed control and cornering is often accomplished by sliding the board wheels and one or both hands on the pavement. The gloves that are used have a palm puck to take the abrasion and dissipate heat. The best gloves have a replaceable puck. Combined with sticky back industrial strength Velcro and Weldwood contact cement, this UHMW at three-quarters of an inch thick is perfect when applied to the leather glove of your choice. I have tested it at over 40 MPH and it shows very little wear (looks more scratched than worn). It is easy to cut with a scroll saw, requiring no special blade. Sanding is no problem with an random orbital sander. The pucks are cut to a 3" diameter circle. At that rate the one foot square will provide me with replaceable pucks for years!

I needed some UHMW to make a router fence. This is good stuff. I thought it was a little warped but realized that the material, by nature, tends to deform. If you take a piece of it and force it into a new shape, it'll hold the shape... For what it's worth, it cuts fine on the table saw, on the router table, on the jointer, etc. Just don't let it burn (obviously) - other than that, it's a snap to machine into whatever you need it for around the shop.

This stuff works great! I ordered a 12''x12''x1/4'' thick sheet. I used it to modify a set of J-hooks in my gym so that they won't damage my bars with metal to metal contact. This UHMW sheet worked great for that purpose. All I did was drill and tap the J-hooks, then countersink the UHMW sheet cut-outs. It's been holding up great for about a month now. There was a ton left over, so if it ever wears out it will be a quick and easy replacement. I don't see them wearing out any time soon though. They have held up great so far.

My use for this material was not conventional. I built a few standing gardens which sit in my pave covered yard, but rather than purchase wheels for something that won't be moving much I used this material cut into 6x6 pads to use as feet. The material is very tough and "gliding" the standing gardens over the pave, while not easy, is at least possible compared dragging the bare wood. The material leaves no marks on the pave, and that's saying something considering the gardens are a good 400lbs each. This material is crazy slick but not *smooth*. You can see the minute pour pattern from the manufacturing process. Personally I consider it smooth, but if you are OCD then the material is simply *slick*. The pattern of pour lines offer zero resistance and I was not able to hold the material vertically in one hand without it immediately escaping my grasp.

sur banc de scie

Good sheet for my purpose but wish the cut is a little bit better, it not exact 12" and it not 90 degree angle

Works well

12 inch square it was not, it is 11.75" square. I could is off by 1/16", even 1/8", but not 1/4".
