At the same time, elasticity, compression set resistance to low temperature is adversely affected. In view of these opposing realities, NBR Seal ring, nitrile rubber o ring seal, NBR rubber seal has good mechanical properties when compared with other elastomers and high wear resistance. NBR Seal ring, nitrile rubber o ring seal, NBR rubber seal is not resistant to weathering and ozone. Some special compound can improve this defect or use NBR/PVC blending compound which has excellent weathering and ozone resistance and good resistant to fuel but compression set is not so good. NBR Seal ring, nitrile rubber o ring seal, NBR rubber seal have excellent resistance to abrasion, non-polar oils and solvent, water and permeation. NBR Seal ring, nitrile rubber o ring seal, NBR rubber seal also can be used in conditions of dilute acids, alkalis and salt solution at low temperatures. Applying in aromatic hydrocarbons, chlorinated hydrocarbons and polar solvents are not suitable.
