Abrasion Resistance

Applications involving oscillation, reciprocation, or rotation induce friction and typically generate wear regions on one surface of the seal. This leads to premature seal failure, system contamination, and eventually system malfunction. When feasible, the use of lubricants, improved surface finishes, or system filtration reduces the effect from friction. However, proper compound selection is essential for extended seal utility.

Best Choice(s)

Carboxilated Nitrile (XNBR) has superior wear resistance properties, when compared to that of the standard Nitrile, through the addition of carboxylic acid groups. Polyurethane also has outstanding resistance to abrasion and is typically employed in high-pressure applications.
