WebThe present invention is directed to a rubber composition comprising: 70 phr to 100 phr of at least one styrene butadiene rubber, 0 phr to 30 phr of at least one further diene-based rubber, from 40 phr to 200 phr of at least one filler, at least 5 phr of aluminum hydroxide, and at least 10 phr of at least one hydrocarbon resin selected from one or more of DCPD … Siloxanes generally adopt structures expected for linked tetrahedral ("sp -like") centers. The Si−O bond length is 1.64 Å (vs Si–C distance of 1.92 Å) and the Si-O-Si angle is rather open at 142.5°. By contrast, the C−O distance in a typical dialkyl ether is much shorter at 1.414(2) Å with a more acute C−O−C angle of 111°. It can be appreciated that the siloxanes would have low barriers for rotation about the Si−O bonds as a consequence of low steric hindrance.
