Depending on compounds and vulcanization conditions an interface can be detected between covulcanized rubbers sheets which exhibits properties different from either of the pure compounds. This interface has been analyzed in NR/SBR covulcanizates by different techniques of NMR imaging including spectroscopic imaging to differentiate different chemical compounds. These investigations were complemented by scanning Fourier infrared spectroscopy and mechanical indentation mapping. The current understanding is that the interface is harder than the SBR and NR regions and typically of the order of 200 μm thick.
