RISInfluence of process variables on chemical devulcanization of sulfur-cured natural rubber
revulcanized samples using 6 phr of BPO, with different reaction times and temperatures were also
investigated. Longer reaction time led to lower crosslink density which in turn caused tensile strength and elongation at break to decrease significantly. Likewise...
Assessment of Failures of Nitrile Rubber Vulcanizates Through High-pressure and High-temperature Gas Media: Effect of Zinc Oxide (ZnO) Nanoparticles,
Most rubber products used in high-pressure and high-temperature gases environment usually suffer from the rapid gas decompression (RGD) failures such as crack, void, bubble, blister, and rupture. Some ingredients of rubber ...
Investigation of the effect of thermal aging on rapid gas decompression (RGD) resistance of nitrile rubber
that thermal aging of NBR vulcanizates strongly depends on crosslink density and mechanical properties. Thermal aging of nitrile rubber samples increased the crosslink density and decreased tensile and tear strength which lead to lower RGD resistance...
Assessment of failures of nitrile rubber vulcanizates in rapid gas decompression (RGD) testing: Effect of physico-mechanical properties
and crosslink density of nitrile rubber (NBR) samples cured by different sulfur curing systems including conventional system (CV), semi-efficient system (SEV) and efficient system (EV) on RGD resistance has been investigated. Results showed that the type...
