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.
