Abstract : Modified SiB-2 rubbers can now be routinely compounded and pressure molded to provide an elastomer having a tensile strength of 450 psi. at ambient temperatures. On testing at 600 deg F, these specimens retain a tensile strength of 30-35% or up to 45% by the addition of Fe2O3 as an antioxidant. At 800 deg F, 10% (and in certain instances l5%) retention was observed. These retention data surpass those reported for silicones and also are better than the corresponding values for Viton B.
