Highly Saturated Nitrile Polymers - Applications in Automotive Shaft Seals

The development of the highly saturated nitrile family of polymers has enabled elastomeric compounds to be developed for both rotating and reciprocating seal applications with good high temperature performance combined with the relatively good low temperature performance associated with conventional nitrile compounds. The paper will discuss a number of compound development programs and illustrate results obtained from both laboratory and seal tests making reference to use of the new compounds in pinion, steering gear and engine seal applications.
