Rulon ® AR is a light maroon colored material best known as the current version of the first Rulon introduced, namely Rulon ® A.
It is somewhat more flexible than Rulon ® LR, hence suitable for seals and bonded coating of slide surfaces. It has many decades of use in automotive shaft seals and fuel metering pump cups.
Rulon ® AR has a practically universal chemical inertness like that of Rulon ® LR and provides long life and reliability in continuous non-lubricated service.
It is capable of operating at PV values up to approximately 10,000. Higher PV values are possible for intermittent use applications.
