| Abrasion Resistance | UHMW PE is the toughest of all plastics. The abrasion resistance of this polymer is equally impressive. In tests where specimens are rotated at 1,750 rpm (revolutions per minute) for 8 hours in 50% sand slurry, UHMW PE exhibits 10 times the abrasion resistance of carbon steel. This is more than double that of 6/6 polyamide and polyurethane and 80 times that of hard neoprene rubber. It is 3 times more abrasion resistant than the toughest elastomer, polyurethane. | ||
* Industry standard testing method using slurry of 60% aluminum oxide and 40% water at a rotation speed of 1750 rpm for 2 hours. Results indicate the ability of each material, in relation to Natural(=100), to resist abrasion under typical UHMW-PE applications. A lower number indicates better abrasion resistance.
