Canyon’s EP75BK28 is a 75 Shore A black EPDM compound that is peroxide cured and specifically formulated for nuclear applications requiring high performance and extremely low extractables. Designed as a nuclear-safe material, it is tested to EN 14582 with ion chromatography and to EPA 3052 with ICP-OES and elemental analysis to verify low problematic elemental content. With a service temperature range of -45°C to 150°C (-49°F to 300°F), EP75BK28 provides reliable resistance to weathering, heat, abrasion, and long-term aging while maintaining low compression set. Its controlled formulation supports stable sealing performance in safety-critical environments where material purity and consistency are essential.
EP75BK28 meets ASTM D2000 5CA715 requirements and is commonly used in nuclear facilities, energy infrastructure, and other regulated environments where low extractables and material traceability are mandatory. The peroxide-cured EPDM chemistry improves thermal stability and aging resistance compared to sulfur-cured alternatives, supporting extended service life under demanding conditions. This compound offers a cost-effective yet highly controlled EPDM solution for nuclear-grade sealing applications.
