a novel mixing approach for achieving a good dispersion of multi-walled carbon nanotubes (mwcnts) in ethylene- propylene diene monomer (epdm) matrix has been investigated. in this approach epdm was modified with vinyltrimethoxysilane (vtms) during melt mixing. in addition the effect of mwcnt concentration on mechanical and rheological properties of modified epdm has been studied. the formulated...

Ethylene-propylene-diene rubbers (EPDM) are one of the most important polyolefin materials widely commercialized and used in various industries recent years. The production EPDM is based solely on catalytic coordination polymerization processes. development new catalysts processes for synthesis has expanded range products their manufacturing terms energy efficiency, processability, environmenta...

Abstract Structure–properties relationship in complex rubber nanocomposites is a key for enlarging the performance window. Herein, halloysite nanotubes (HNTs) are added at variable content to ethylene-propylene diene monomer (EPDM)/nitrile butadiene (NBR) blends compatibilized with maleic anhydride grafted HNTs evaluate cure characteristics, along microstructure, and mechanical swelling behavio...

Temperature scanning stress relaxation (TSSR) measurement of peroxide vulcanized polymer blends polypropylene (PP) and ultrahigh molecular-EPDM (UHM-EPDM) rubber has been performed to study the thermomechanical behavior thermoplastic vulcanizates (TPVs). Co-agents play crucial roles in enhancement properties TPVs. Different types co-agents (Triallyl cyanurate-TAC; N, N-m-phenylene-dimaleimide-H...

To study the effect of nano-silica particles on conductivity characteristics ethylene propylene diene monomer (EPDM) insulation, EPDM nanocomposites with different mass fractions nano silica were prepared via melt-blending method. Scanning electron microscopy was used to analyze dispersion nanoparticles in EPDM. Based Fourier-transform infrared spectrum, bonding properties between and analyzed....

Neste trabalho, a poliamida 6 (PA6) foi tenacificada com o terpolímero de acrilonitrila-EPDM-estireno (AES), utilizando etileno-propileno-dieno enxertado anidrido maleico (EPDM-MA), como agente compatibilizante. As blendas foram preparadas em uma extrusora rosca dupla corrotacional e, posteriormente, moldadas por injeção. propriedades resistência ao impacto, à tração e morfologia avaliadas. Os ...

A novel mixing approach for achieving a good dispersion of multi-walled carbon nanotubes (MWCNTs) in ethylene- propylene diene monomer (EPDM) matrix has been investigated. In this approach EPDM was modified with vinyltrimethoxysilane (VTMS) during melt mixing. In addition the effect of MWCNT concentration on mechanical and rheological properties of modified EPDM has been studied. The formulated...

Abstract The performance change of Ethylene propylene diene monomer (EPDM) was studied by the accelerated aging experimental method, and its lifespan predicted. results showed that thermal oxidation EPDM is dominated crosslinking reaction. With extension time, total density tensile permanent deformation gradually decrease, while strength hardness increase gradually. life prediction formula unde...

This study was to develop a radiation sterilized polypropylene/ethylene-propylene diene monomer (PP/EPDM) binary blends using melt blending and the mechanical properties of were studied. The PP/EPDM prepared in ratios 80:20, 60:40, 50:50, 40:60 20:80. then compressed for 12 minutes Hot Cold Press machine cut into 1mm, 3mm 6mm thickness tensile test, impact hardness test Fourier Transform Infrar...
