* 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.
The information listed herein is stated to the best of our knowledge and
is intended to provide a general guideline for UHMW PE and its uses. The
values given are based on laboratory testing backed with global industry
experience. All properties in this table have performed equal or better
in laboratory testing. However, the data should not be considered as
guaranteed specific properties. Suggested applications are provided for
information only and are not specific recommendations.
