摘要：
An improved treatment for reinforcing silica uses both a silazane represented by the formula (RR'R"Si).sub.2 NH and bis-Si-(1-methyl-1-silacyclopentenyl) amine as filler treatment. The filler treatment may be done either in situ during the manufacture of curable silicone elastomer compositions or as a separate operation. The treatment allows production of an easily extrudable composition with improved durometer and tear strength.
