Abstract
The effects of temperature and curing systems on the compression set of natural rubber (NR) at constant load were investigated. NR was compounded with various amounts of sulfur and DCP in order to obtain various crosslink densities and curing systems. Compression sets at constant load were compared with those at constant strain. Compression set at constant load was more affected by changes in crosslink density than compression set at constant strain, due to the differences of exerted strain energy density. Compression set of sulfur cured NR under constant load was increased with increasing load and temperature, but the compression set of DCP cured NR was not changed by increasing load and temperature.
