3.5. Dynamic properties
Heat build-up and dynamic compression set of silica/NR
composites, illustrated in Figs. 14 and 15, respectively,
progressively increase with increasing silica loading due to
the dilution effect. Furthermore, FSi/NR composites give
higher heat build-up and compression set than those of PSi/
NR composites, particularly at 30 phr FSi and without Si-69.
