NE60BK51 Datasheet

NE60BK51 is Canyon’s MIL-R-6855 compliant 60 Shore A black Neoprene (CR) compound engineered for O-rings and gaskets requiring reliable low-temperature performance and superior compression set resistance. This material offers good resistance to weathering, moderate heat, and low-temperature solvents and refrigerants, supporting consistent sealing in aerospace, military, and industrial environments. With a service temperature range of -40°C to 125°C (-40°F to 257°F), NE60BK51 maintains elasticity and sealing force through temperature cycling in static and light dynamic applications. Its mid-range durometer balances conformability with improved extrusion resistance for dependable long-term service. Compare NE60BK51 to Parker C1124-70 for similar specification-driven, low-temperature Neoprene sealing performance.

 

NE60BK51 meets ASTM D2000 5BC610 requirements and MIL-R-6855 Class 2, Type A and B, Grade 60, making it suitable for qualified programs that require documented compliance and repeatable material properties. This compound is commonly selected for applications prioritizing cold-service capability, environmental durability, and value without transitioning to higher-cost fluorinated elastomers.
