Canyon’s EP70BK80 is a 70 Shore A black EPDM compound that is peroxide cured and engineered for sanitary sealing applications in food, pharmaceutical, and medical environments. It is compliant with USP Class VI <87> and <88>, FDA 21 CFR 177.2600, and 3-A Sanitary 18-03 Class 2, making it suitable for regulated processes that require hygienic materials and traceability. With a service temperature range of -40°C to 150°C (-40°F to 300°F), EP70BK80 delivers reliable resistance to weathering, heat, abrasion, and compression set while maintaining high elasticity and sealing integrity. Its ADI, BSE, and TSE-free formulation supports use in sensitive applications where material purity and safety are critical.
EP70BK80 is commonly used in food processing equipment, pharmaceutical systems, and medical devices that undergo frequent cleaning and thermal cycling. The peroxide-cured EPDM chemistry improves aging stability and consistency compared to sulfur-cured alternatives, supporting long service life in demanding sanitary environments. This material is often cross-referenced as an alternative to Parker E3609-70 for similar high-compliance EPDM sealing applications. Canyon Components also offers additional peroxide-cured EPDM options to meet varying temperature, regulatory, and performance requirements.
