适用范围
This specification covers a fuel and low-temperature resistant butadiene- acrylonitrile (NBR) rubber in the form of molded rings. These rings have been used typically for gland type packings and seals in flexible couplings for use at temperatures from -55 degrees to 100 degrees C (-67 to 212 degrees F) where resistance to fuel is required, but usage is not limited to such applications.
