Nitrile (BUNA-N), is a general purpose copolymer of butadiene and acrylonitrile. This compound has a relatively high acrylo content, making it exceptionally resistant to petroleum base oils and hydrocarbon fuels over a temperature range of -40F to +250F. It is the seal industry’s most widely used and economical elastomer. It also has a good balance of desirable working properties like low compression set, high abrasion resistance and high tensile strength.
➤ Temperature Range: -35 °C to 100 °C which makes it ideal choice for automobile applications
➤ Excellent abrasion and tear resistance.
➤ Good rebound properties
➤ Good non-polar solvent resistance.
➤ Good resistance to fluids like water and oil
➤ Cheaper than most types of Synthetic Elastomers and fluoroelastomers
