NBR/PVC compounds are homogenous butadiene and acrylonitrile copolymer blends with PVC that uses CA/ZN based stabilizers. NBR/PVC blends are recommended for applications that require good resistance to the elements and organic liquids, such as aliphatic oils and nonpolar solvents. Its main advantage over traditional nitrile rubber is its ozone resistance.
