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...

Porous asphalt pavements are environmentally friendly permeable road pavements. There is a need to improve the strength performance of porous mixtures. Waste Ethylene Propylene Diene Monomer (EPDM) rubber modification mixtures investigated in this study. The mixture was initially designed for selected mix aggregate gradation. EPDM scraps were replaced with filler materials at rate 2 % and 4 tot...

A series of 8 new complexes of titanium and zirconium with diamido ligands bearing an ethylene and propylene bridge between the two amido groups were synthesized and tested for ethylene polymerization. Titanium complexes bearing an ethylene bridge between the two amido groups showed higher activities than the derivatives with a propylene bridge. In the case of the zirconium complexes, the p...

bis(indenyl)zirconium dichloride as a catalyst was synthesized using a modified method at the room temperature. polymerization of ethylene and copolymerization of ethylene and propylene were carried out by this metallocene catalyst. ethylene propylene (p/e) feed ratios of 0.25, 0.5, 1, and 2 were employed into the copolymerization systems. copolymerization conditions like cocatalyst/catalyst ra...

In this work, rubber nanocomposites based on natural rubber/ethylene propylene diene monomer (NR/EPDM) blends and reinforced with nanosilica (NS) in combination carbon black (CB) barium sulfate (BS) were prepared by melt blending method a Brabender internal mixer. The appropriate contents of NS CB for reinforcing the NR/EPDM are 10 30 phr (parts per hundred rubber), respectively. material has b...
