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...

An effort was made to improve the separation issue of styrene-butadiene-styrene modifiers in styrene-butadiene-styrene-modified asphalt binders and further enhance their performance by adding nano-ZnO binder prepare compound modified binder. First, optimum dosage determined based on conventional tests, i.e., penetration, ring ball softening point, ductility at a fixed dosage; then, dynamic shea...

Dynamic mechanical properties including temperature effect, stress softening, and Payne effect are studied on the elastomer composites filled with soy protein or carbon black. The comparison of protein composite with well-known carbon black composites provides further insight into the protein composites. The elastomers filled with soy protein aggregates give substantial reinforcement effect whe...

Waste materials such as waste tire rubber (WTR), cooking oil (WCO), bio-oils, engine (WEO), and other oils have been the subject of various scientific studies in sustainable research field. The current environmental concerns identified to protect natural resources reuse materials. Accordingly, this work reviews use recycled mixed with (waste oil, oil) bio-oils that can be extracted from rejuven...

Along with the developing technology in rubber industry, use of natural and synthetic rubbers as well liquid has increased significantly recent years. The formulation tread compound, which directly affects performance a tire, is generally produced from rubbers. Intensive scientific studies have been carried out on because they reduce consumption process oils used tire production phase increase ...

The main objective of the current research work is to explore effect nanosilica particles on compound EPDM/SBR-SiO2 (ethylene-propylene-diene monomer/styrene-butadiene rubber-nanosilica). composite EPDM/SBR with and without silane coupling agent was processed using an open mill mixer. are prepared in laboratory were used as reinforcing material rubber composites. cure characteristics, mechanica...
