Conventional bearing systems and materials, which are important components of machine elements, have often failed to fulfil requirements, especially in places where sealing is required. In such cases, sliding bearings with PTFE- NBR-based polymer elastomer materials operating water or oil preferred. this study, the performance two alternative rubber-based synthetic styrene butadiene rubber (SBR...

The effect of octaisobutyl-polyhedral oligomeric silsesquioxane (OIB-POSS) as a nanosized reinforcement on the cure kinetics, crosslinking density, and mechanical properties styrene-butadiene rubber (SBR) nanocomposites was examined in this study. For purpose, SBR compounds with various OIB-POSS nanoparticle loadings at 1, 3, 5 phr were prepared their results compared reference compound without...

Ethylene Propylene Diene rubber (EPDM), is present in many applications. However, its crosslinked structure makes difficult recycling. The use of devulcanized EPDM, (dEPDM) as a component elastomeric composites, real possibility to reuse EPDM scraps. In this study, three matrices (natural (NR), styrene butadiene (SBR) and rubber) have been tested including recycled component. previously was usi...

The influence of styrene butadiene rubber (SBR) or low-density polyethylene (LDPE) polymers on the characteristics local asphalt binder was analyzed to characterize rheological properties. results indicated that SBR LDPE increased softening point. point enhanced by around 35% when 9% used in comparison unmodified asphalt, while there a 15% increment used. also decreased penetration rate. decrea...

The influences of nanosilica and modified on cure, compression set, mechanical swelling characteristics are studied in blends ethylene-propylene-diene monomer (EPDM)/styrene-butadiene rubber (SBR). In EPDM/SBR composites, the made from rice husk ash (RHA) was utilised as a reinforcing nanofiller. interaction between matrix at interface is crucial for production composites. This study uses bis[3...

Blending of rubber is an important route to modify properties individual elastomeric components in order obtain optimum chemical, physical, and mechanical properties. In this study, a novel modification styrene butadiene (SBR) made by employing acrylic (ACM) blends outstanding mechanical, dynamic, oil resistance achieve those properties, we used unique vulcanizing system that improves the cross...

The functionalization of elastomers by phosphonate groups remains relatively unexplored considering the great potential these polymers would represent for applications. In this paper, thiol-functional oligophosphonates were designed and coupled a thiol-ene reaction to styrene-butadiene rubber (SBR). We adopted RAFT methodology with dimethyl vinylphosphonate (DMVP) high-temperature thermolysable...

Modifying asphalt binder with styrene butadiene rubber (SBR) improves low temperature performance (resistance to cracking), elastic recovery, and ductility of binder. However, some difficulties were found at high temperatures susceptibility (Rutting), storage stability (compatibility). Therefore, the aim this study is resolve these defects (rutting compatibility) by formulating SBR/ waste nanoc...

In this paper, micro-mechanical properties of styrene–butadiene rubber (SBR) latexmodified cement pastes identified by means of the nanoindentation (NI) technique are related to macro-mechanical properties of SBR latex-modified mortars obtained from standard test methods, considering an SBR latex/cement ratio varying from 0% to 20%. For this purpose, the average value of the hardness and the so...
