2.3. Cure characteristics
The cure characteristics of the CB-filled SMR-L compounds with
and without ALK at various curing systems were obtained using a
Monsanto Moving Die Rheometer (MDR 2000), which was
employed to determine the scorch time (ts2), cure time (t90) and
torque difference (MHdML) according to ISO 3417. Samples of the
respective compounds were tested at 150 C. The CB-filled SMR-L
compounds were subsequently compression-moulded using a
stainless steel mould at 150 C, with a pressure of 10 MPa, and
applying a laboratory hot-press based on respective curing times.
