Beschreibung
Zusammenfassung:	The invention relates to a roll cover which is suitable in particular for a roll for treating a paper, cardboard, or other fibrous material web in a machine for producing and/or finishing same and which comprises at least one layer. The at least one layer contains a rubber composition which contains a rubber component comprising at least one crosslinked hydrogenated nitrile rubber and which contains at least one (meth)acrylate compound, and the at least one layer has a) a resilience speed of at least 12 mm/sec and/or a plastic deformation degree of maximally 0.9%, and b) a tan delta value of maximally 0.16 determined in accordance with DIN 53513 at 60 DEG C, under a tensile strength, at 10 Hz, and with a static elongation of 15% and a dynamic elongation of 1%.
