*Industry standard testing method using a slurry of 60% aluminum oxide and 40% water at a rotation speed of 1,750 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.
