Re: [T3] Seat Rails

<x-flowed UTF-8>My local plastic shop has some UHMW-PE (Ultra High Molecular Weight 
Polyethylene) plastic that is designed for this application. This stuff 
is really heavy, a lot heavier than HDPE (cutting board material)

Quote:

"UHMW-PE (Ultra High Molecular Weight Polyethylene). This is a polymer 
with a molecular weight of 3 and 6 million. UHMW-PE has outstanding 
abrasion resistance, low coefficient of friction, self-lubricating, 
chemical and stress cracking resistance. Another key characteristic is 
impact strength, which is 8 times greater than HDPE. UHMW-PE does not 
break in impact tests using standard notched specimens compared to 
HDPE, which will break. UHMW-PE must be double notched to break in a 
Izod impact test. In a ballistics test conducted at -65ÏF, a 1â slab 
of UHMW-PE stopped a .45 caliber bullet at a distance of only 25 ft!

ApplicationsÂ: Conveyor wear strips, Guide rails, Bearings, Paper 
machine suction boxes, Chute linings, Trailer linings, Snowmobile skis, 
sliders, idler wheels, drive sprockets & suspension bushings.
