High performance industry standard elastomers for nuclear applications requiring resistance to ionising radiation.
In addition to our own compounds and materials that we have developed for customers, James Walker has a long history of expertise in processing industry standard materials and customer specific materials such as EPDM 30H.
When selecting an elastomer for duties with ionising radiation, it is important to consider other factors in addition to radiation resistance. For example, the elastomer should also be evaluated for physical robustness, chemical compatibility and resistance, and temperature performance in the operational environment.
We regularly compound and/or mould the following elastomers for nuclear duties. A number of these materials are specific to particular customers, as indicated, and cannot otherwise be supplied without their authority.
