The blends of polyurethane elastomer (AU) with hydrogenated nitrile rubbers (HNBR) prepared by different blending techniques and different blend ratios have been studied. The processability and weather resistant properties of polyurethane elastomer was improved by blending with HNBR. Blend properties largely depend on the blend ratios and blending techniques. IR spectral analysis suggested interchain crosslinking by thermal activation between AU and HNBR. Preheating of the preblends before adding curatives improved the properties of the blends. The thermal stability of the blends were also improved. Preheating restricted the extractibility of the phases by solvent extraction as confirmed by the SEM analysis. |
