Abstract:

A compounded elastomer comprising an elastomeric resin, a first carbon black, and a second carbon black different from the first carbon black. The second carbon black is a partially crystallized carbon black having an OAN structure of greater than 120 cm.sup.3/100 g and less than 200 cm.sup.3/100 g, a surface energy of less than 10 mJ/m.sup.2 and a Raman microcrystalline planar size (L.sub.a) of greater than or equal to 25 .ANG. and less than or equal to 50 .ANG..
