Canyon’s EP90BK10 is a 90 Shore A black EPDM compound engineered as a high-durometer, cost-effective sealing material for demanding industrial environments. Its higher hardness provides improved extrusion resistance and dimensional stability, while maintaining good heat resistance, abrasion resistance, and low compression set for long-term sealing performance. With a service temperature range of -55°C to 130°C (-67°F to 266°F), EP90BK10 performs reliably in outdoor and industrial applications where resistance to weathering, ozone, and environmental exposure is required. The compound’s balanced mechanical properties support dependable performance in static and moderate dynamic sealing conditions.
EP90BK10 meets ASTM D2000 M4BA810 requirements and is commonly used in industrial equipment, enclosures, and general-purpose sealing applications that benefit from a stiffer EPDM material. It is frequently cross-referenced as an alternative to Parker E0652-90 for similar high-durometer EPDM sealing needs. Canyon Components also offers additional EPDM formulations with different cure systems, durometers, and performance profiles to support specific application requirements.
