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...

Dynamic compressive stress-strain curves at various strain rates of an EthylenePropylene-Diene Monomer Copolymer (EPDM) rubber have been determined with a modified split Hopkinson pressure bar (SHPB). The use of a pulse-shaping technique ensures that the specimen deforms at a nearly constant strain rate under dynamically equilibrated stress. The validity of the experiments was monitored by a hi...

Abstract Multi‐walled carbon nanotubes (MWCNT) were first non‐covalently functioned by tannic acid (TA), then blended with nitrile rubber (NBR) and ethylene propylene diene monomer (EPDM) NBR:EPDM:TA‐MWCNT = 70:30:5. TA‐MWCNT the composites had been characterized various techniques, including Fourier transform infrared spectroscopy (FT‐IR), Raman analysis, transmission electron microscopy (TEM)...
