Abstract
Elastomer compositions comprising an elastomer gum curable to the solid, elastomeric state in the presence of an organic peroxide free radical initiator, a solid particulate filler, a hydrocarbon resin having a plurality of pendant vinyl groups per molecule, and an organic peroxide curative are described. Vulcanizates of such compositions are also described. Preferred are elastomer compositions comprising a fluoroelastomer gum curable to the solid, elastomeric state in the presence of an organic peroxide cure initiator and a carbonaceous filler coated with a 1,2-polybutadiene resin. Solid particulate fillers coated with a hydrocarbon resin having a plurality of pendant vinyl groups per molecule, such as 1,2-polybutadiene, are also described.
