Radiation-resistant rubber seals

Any information related to leakage of radioactively contaminated fluids that results from rubber seal failure, and the effects and dosage levels on humans is useful and should be considered when designing a radiation-resistant rubber O ring or seal. In order to extend the life of rubber seals or O rings in a radioactive environment, hence reducing waste, and the amount of radiation to which the operators are exposed, it is necessary to develop and use highly radiation-resistant rubbers. Many rubber seals manufacturers have done this. 

The use of EPDM rubbers for the manufacture of automobile and truck tires has not been successful, mainly because of poor tire cord adhesion and poor compatibility with most other rubbers. However, EPDM rubbers have become widely accepted as a moderately heat-resisting material with good weathering, oxygen, and ozone resistance. They find extensive use in nontire automobile applications, including body and chassis parts, car bumpers, radiator and heater hoses, weatherstrips, seals, and mats. Other applications include wire and cable insulation, appliance parts, hoses, gaskets and seals, and coated fabrics.
