Carboxylated Nitrile Butadiene Rubber (XNBR), 65-75 °IRHD. Terpolymer of acrylonitrile, butadiene and methacrylic acid. Applications: Carboxylated Nitrile (XNBR) offers much higher modulus, increased tensile strength and superior abrasion and tear resistance over standard NBR. Widely used in applications requiring oil resistance, high strength and abrasion resistance. |
