nanocomposite samples based on elastomer blends of butyl rubber (iir) and ethylene propylene diene monomer (epdm) were prepared using a laboratory scale two-roll mill in order to study the effect of cloisite 15a organoclay content (i.e., 1, 3, 5 and 7 wt%) on the mechanical and morphological properties  of  iir/epdm/cloisite  15a  nanocomposites  compared  to  the  unflled epdm/iir blends. rheo...

The current research presentsthe development of EPDM rubber including shape memory alloy. Cu-Al-Zn alloy was modified with the coupling agent3-(Trimethoxysilyl) propyl methacrylate (TMSPM)and then incorporated into Ethylene propylene diene (EPDM) by a 2-roll mill technique.The Cu-alloy behaved as superelasticity capability which can be used in various engineering approaches to smart materials. ...

Abstract Improper disposal and accumulation of waste tire rubbers have posed a serious threat to the development circular economy, sustainable environment, human health. In light drawback current management tires, recycling transformation reclaimed rubber (RR) into valuable end products has received significant attention from industries academic field. Herein, we propose facile method reuse RR ...

Because these reactive sites are pendant (not part of the main backbone chain) there are no weak points on the main chain. This is unlike for example Natural Rubber or SBR, where these necessary reactive sites are along the main chain. This means that reactive entities in the atmosphere (for example Ozone, which is very aggressive) can easily attack and degrade these materials. This also explai...

Uniaxial and biaxial cyclic tensile tests stress relaxation were performed on the ethylene propylene diene monomer (EPDM) material to investigate its stress-softening effect. The experimental results reveal that EPDM presents a significant Mullins effect during stretching processes. Furthermore, it is found deformation of does not return zero simultaneously with stress, due viscoelasticity mate...
