Abstract
Official abstract text for this publication.
The present invention relates to an elastomeric composition containing a nitrile rubber, preferably hydrogenated, and a filler. Compositions according to the present invention have high filler levels, excellent processability, and very good resistance to aggressive fluids and fuels compared to known HNBR compositions.
First claim
Opening claim text (preview).
The invention claimed is: 1. An elastomeric composition comprising a hydrogenated nitrile rubber (HNBR) and a carbon black filler, wherein the filler is present in an amount of 200 to 500 parts per hundred rubber and wherein the hydrogenated nitrile rubber has a Mooney viscosity of a maximum 55 (ML1+4 @ 100° C.). 2. The composition according to claim 1 , wherein the hydrogenated nitrile rubber has a Mooney viscosity below 30 (ML(1+4)@ 100° C.).…
