Book Description
The effect various carbon black and other fillers have on the radiation resistance of a nitrile (acrylonitrilebutadiene copolymer) elastomer is discussed and supported by data. All of the compounds were exposed to gamma radiation in air at 25 deg C and normal atmospheric pressure to doses ranging up to 5 x l0/sup 8/ r. Results show that both hardness and tensile strength are affected in varying degrees with respect to compounds within a filler series and compounds of different series compared on an equal loading basis. The elongation, on the other hand, was essentially the same based upon percent change. The only consistent behavior noted among the various nitrile compounds was the extreme rise in tensile strength after exposure of 3 x 10/sup 8/ r with accompanying loss of elongation and severe embrittlement.
