Several comments on from earlier posts in thread. UHMW-PE is NOT the equivalent of Teflon (PTFE). UHMW is *much* stronger but slightly less slippey than Teflon. Teflon has less friction than UHMW, but is not nearly as strong to impacts. Use UHMW for reducing friction and anti-snow sticking in blowers - a 1" thick piece of UHMW will stop a 45 Auto (don't stand behind the plastic to test this! :c)
UHME, being mechanically strong, does not heat form well to compound curves (at least not without a compound curved heated mold). If you need to cover a compound curve, individual pieces may be used if the curved area, like the deflector on my blower, is comprised of simple curves welded together. UHMW does heat form easily to make simple bends. Heat until white UHMW starts to go clear, or goes almost so. Bend to desired angle and hold in place until it cools (you can spray with water to cool it quicker, or in some apps, clamp it in place until cool).
To determine dimensions of piece to cut for chute, for example, cut a narrow strip of the plastic and use a heat gun to form and clamp the strip in place. This will allow you to adjust the dimensions for the material "taken up" in forming the bend. With the test strip in place, use felt tip to mark center of each corner bend as well as the ends of that bend. This strip will serve as a guide for laying out the actual piece. (UHMW it too expensive to goof and waste that way.)
Most adhesives or caulk will not adhere UHMW to whatever. UHMW tapes, with acrylic adhesives are available, but even 10 mil or a bit thicker is not thick enough to withstand stone or gravel impacts in this application, resulting in tears (I tried it on the inside of the deflector and it lasted a few hours) - it would last if you never pick up debris.
I used 1/8" thick sheet on my tractor mounted blower. Used #8 screws. For longer lengths, be aware that UHMW has a much higher coefficient of expansion than does steel. So for a blower housing liner, you may have to attach one end fixed, while mounting the other with a slot in the plastic so it can lengthen or contract (I tested a roughly 5' length by putting it in freezer - measuring, then putting it in the hot tub (102*F). As I recall, delta-length was at least 1/2". BTW, the blower liner finally failed due to picking up a rock that impacted the acute bend of the liner whee as the impeller blade passes the chute opening to again enters the housing - kept working for one season in spite of the tear, but finally came loose.
The UHMW-PE the chute liner gained about 25% throw distance - good, and the chute doesn't clog. I'm not going to replace the blower housing liner just yet. It was a lot of work to make and install and that leading edge area, where it tore, would need a stainless steel guard. With the lijner gone, I've got 1/8" more of a gap to seal at the blades. I'm going to make seals, but instead of rubber, I'm using 1/8" UHMW-PE. Much stiffer than rubber, so I'm gonna have to just fill the gap, not much more. Advantage is I can make the "seal" to cover the whole face of the blade, so the blades won't clog in the slushy stuff.
Here's a short vid of throw distance with medium density snow.
