An environmentally durable elastomer composition with excellent low temperature dynamic properties

摘要

This invention relates to an environmentally durable composition which has excellent low temperature dynamic properties. The composition comprises a substantially homogeneous mixture of 100 parts by weight elastomer having a fully saturated backbone, curing agent for the elastomer in amounts sufficient to crosslink the elastomer, reinforcing particulate filler and at least 20 parts by weight of an aliphatic oil. The aliphatic oil modifies the low temperature dynamic properties of the elastomer. Particulate graphite may be incorporated into the composition to lower its friction.
