3.6.1. Mechanical properties
Depending on the data obtained before, Tables 1–4, comparison
can be established between NBR cured by DCP/coagent, (P1 PFM)
with that cured by electron beam radiation/coagent, (R150 PFM)
at comparable values of Vr 0.37. The physical properties of the
vulcanizates are illustrated in Table 8. Comparable values for hardness,
Eb, tearing strength, soluble fraction SF, Q, Mc and cross-link
density were recorded for these two vulcanizates, whereas the vulcanizate
samples cured by radiation/coagent gave higher values of
TS and tensile modulus. The behavior of the latter is due to the increase
in cross-link density.
