The
abrasion resistance of Keltrol's TUFLAR™
polymers is illustrated in the sand-slurry diagram below. These
tests were conducted for a period of 7.5 hours at a speed of
1750 rpms. Results for conventional wear resistant materials
are expressed as a percentage based on the volume of material
lost. A carbon steel standard was assigned a value of 100. The
lower values represent an increased resistance to abrasion.
The data clearly indicates the superior performance of Keltrol's
TUFLAR™
in wear resistance. |
