Precision Polymer N93B

About
N93B is a Copolymer of acrylonitrile and butadiene with a medium ACN content of 30 – 45%. NBR materials typically provide excellent resistance to petroleum-based oils, fuels and greases, as well as, very low gas permeability, ozone resistance, plus exceptional heat ageing and mechanical properties. N93B is accepted by the UK Ministry of Defence (MOD) to Defence Standard 02-337 part 1, issue 1 (NES 337) for use on naval ships and submarines. Material code MN90. Available in any sized O-ring (fully moulded up to 2.5m/8ft internal diameter) and custom designed components. Key Attributes Excellent resistance to aliphatic hydrocarbon oils, fuels and greases. Very low gas permeability Accepted by M.O.D. to Def. Stan. NES 337 Typical Applications Naval ships and submarines Aerospace Applications&&
