DEVELOPMENT OF RUBBER GASKETS WHICH ARE RESISTANT TO NUCLEAR RADIATION. Final Report. Report No. 149-4
Vulcanizates were developed which are suitable for gasket service in gamma nadiation up to a dosage of 10/sup 8/ r. The rubbers most satisfactory for this purpose are natural rubber, styrene/butadiene copolymers (particularly with 21.5% styrene polymerized at 41 deg F), and acrylonitrile/butadiene/methacrylic adid terpolymers. The choice of the rubber to be used depends on the fluid to be sealed. The resistance to radioinduced compression set can be enhanced by compounding the rubbers with antioxidants or antiozonants and/or with certain chemicals containing aromatic rings or condensed ring structures. The resistance of a styrene/butadiene vulcanizate to gamma radiation is improved if dicumyl peroxide is used as the vulcanizing agent in lieu of sulfur. (D.L.C.)
