Tensile and Dynamic Mechanical Properties of Natural ...
[3]. When strontium ferrite was used as an alternative for hard ferrite filler, the tensile strength and elongation at break of the NR were also reduced [4]. Similarly, soft ferrites such as nickel cobalt zinc ferrite and manganese zinc ferrite act as nonreinforced fillers and inhibit the stressinduced crystallization in rubbers [5,6].

rium ferrite (BaFe 12O 19) or strontium ferrite (SrFe 12O 19) have been used as fillers. Barium ferrite–NR composites prepared by the tworoll mill technique possessed large (BH) max but the tensile strength was reduced with increasing magnetic loading (Makled et al 2005). Like soft ferrites, hard ferrites also acted as nonreinforced fillers
