Another seal, which is high in demand and manufactured by Offshore Seals, is NBR Seal. NBR is a polymer from butadiene and acrylonitrile. These seals have a high strength and excellent resistance against abrasion, when carbon black is used as filler. NBR seals with bright color are produced with mineral fillers and active silicate fillers. These manufactured seals have also good strength. NBR materials have a better swelling resistance against animal and vegetable greases and oils than silicone rubber. In comparison to silicone rubber, NBR Seals has the lower temperature resistance. They are mainly suitable for air, gas, and oil at low temperatures. NBR seals are good for general industrial application. The company supplies them in different hardness and sizes and also customizes these Seals in various type of profile.
