Nitrile rubber 1-14 INDEX

In one experiment 17.7 grams of nitrile rubber were Immersed In 200 ml Indolene HO-III for 72 hours. The Index of refraction of the Indolene was 1.4294 before Immersion and 1.4298 after Immersion. This means that the Immersion of rubber In the Indolene did not significantly change the Index of refraction. 

Other work that has looked into the performance of recovered black includes a Malaysian investigation [17] that evaluated the performance of the black in NR and nitrile rubber (NBR) formulations. The curing characteristics, physical properties and swelling index of the rubber compounds were investigated and compared with those of rubber compounds containing virgin black. In the case of the NBR compounds, blends of the recovered black with virgin black were also prepared and tested. 

Nitrile rubber (NBR)-clay nanocomposites were prepared by different methods.The NBR-clay nanocomposites exhibited excellent gas barrier properties. Compared to gum NBR vulcanizate, the oxygen index of the NBR-clay nanocomposites slightly increased. " ...
