Good physical properties and chemical resistance to the most common hydraulic fluids makes NBR an excellent sealing material.
2 NBR materials are one of the most commonly used elastomers in sealing properties mentioned are only valid for test pieces of the corresponding ISO, DIN and ASTM standards. They Cannot be directly related to finished seals, gaskets or other sealing products and should only be used as a general : 0114 243 2777 Fax: 0114 242 2300 Email.
