BAYER PRESENTS TECHNICAL PAPER ON CARBOXYLATED NITRILE RUBBER AT ACS RUBBER EXPO 03
14 October 2003 - Bayer MaterialScience AG
| Carboxylated nitrile rubbers (XNBR) are terpolymers of acrylonitrile, butadiene and an organic acid monomer. |
Although cured by conventional systems, the introduction of pendant carboxyl groups allows the formation of reinforcing ionic linkages, or clusters, at these sites to provide tough vulcanizates with usually higher strength and abrasion resistance. In addition to their strength properties, carboxylated nitrile rubbers have similar resistance to heat, oil, and fuels as regular nitrile rubbers. A review of cross-linking systems and their effect on various properties of carboxylated nitrile rubbers is the focus of this paper.
