Abstract:
Fine particles of barium ferrite (BaFe12O19) belonging to the M-type hexagonal ferrites were prepared by the
conventional ceramic techniques. They were incorporated into a nitrile rubber matrix according to a specific recipe for
various loadings to produce rubber ferrite composites (RFC). The percolation threshold is not reached for a maximum
loading of 130 phr (parts per hundred rubber). Here in this paper, the magnetic properties and processability of the nitrile
rubber based RFCs containing barium ferrite (BaF) and HAF carbon black is reported. The magnetic properties of the
ceramic ferrite and these rubber ferrite composites were evaluated and it was found that the coercivity values of RFCs were
less than that of the ceramic BaF, but remained constant with the loading of both the ferrite filler and carbon black.
However, other properties like saturation magnetization and magnetic remanence increased with the loading of ferrite filler.

Abstract:
A carbon black filled 50/50 natural rubber (NR)/styrene-butadiene rubber (SBR)
blend is vulcanized using several conventional curing systems designed by varying the
amounts of sulphur and accelerator. The cure characteristics and the properties of the
vulcanizates are compared. The quantity and quality of crosslinks in each case are
evaluated by chemical probes to correlate them with the properties.
