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 organo-metal salt of aluminum triacrylate (alta) with a general formula of (ch2=chcoo)3al was  synthesized  as  a  reactive  fller  for  elastomers through a two-step synthetic procedure. fourier transform-infrared spectroscopy (ftir), dsc and dta were employed for alta analysis and to study its cure characteristics. in this research, two composites based on ethylene propylene diene monomer...

Rather than using graphene oxide, which is limited by a high defect concentration and cost due to oxidation and reduction, we adopted cost-effective, 3.56 nm thick graphene platelets (GnPs) of high structural integrity to melt compound with an elastomer-ethylene-propylene-diene monomer rubber (EPDM)-using an industrial facility. An elastomer is an amorphous, chemically crosslinked polymer gener...

Ethylene-propylene-diene rubber (EPDM) is a elastomer widely used in common industrial applications. EPDM can be shaped into sheets and employed as isolating material for roofing systems. In this study, scraps of from commercial, residential systems were treated by combined thermo-mechanical microwave devulcanization processes including peroxide benzoyl (BPO). The devulcanized (Dev-EPDM) was ch...

This study used ethylene-propylene diene monomers (EPDM), an elastomer, to develop foams incorporating clay as filler using simple compounding, chemical foaming, and peroxide-mediated light crosslinking methods. The low-temperature batch mixer was employed for compounding azodicarbonamide (ADC) a foaming agent, dicumyl peroxide (DCP) crosslinker, followed by compression molding sheet preparatio...

Thermoplastic elastomers are a special class of polymeric materials that combine the properties of thermo plasticity during processing and rubber-like behaviour in service. They can be processed in conventional plastic processing equipment, such as twin screw extruders, internal batch mixers, extruders and injection moulding machine, but exhibit vulcanized rubber like ultimate properties (i.e. ...

Poliamit-6 polimerine ilave edilen EPDM elastomeri, malzemenin çekme dayanımı ve elastiklik modülü gibi değerlerini azaltırken cam elyaflar kompozitin kopma uzamasını azaltmaktadır. Dolayısıyla endüstrinin talep ettiği yüksek mekanik özelliklere yani mukavemet, rijitlik üstün kırılma tokluğu (darbe enerjisi) sahip kompozitlerin elde edilebilmesi için elastomer elyaf takviyeli polimer birlikte ü...
