One of the significant problems our time and future is environmental pollution. There are many factors that cause pollution main concerns waste material. Since production, consumption service activities have increased with rapid industrialization increasing population. Waste assessment a process includes minimization, separate collection at source, intermediate storage, pre-treatment, establish...

New materials capable of storing thermal energy in view building applications have been developed from the foaming ethylene-propylene diene monomer (EPDM) rubber with addition paraffin as a phase change material (PCM) at melting temperature about 21°C. Considering that EPDM foams prepared by using traditional chemical blowing agents are generally characterized rather elevated environmental load...

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...

Ethylene Propylene Diene rubber (EPDM), is present in many applications. However, its crosslinked structure makes difficult recycling. The use of devulcanized EPDM, (dEPDM) as a component elastomeric composites, real possibility to reuse EPDM scraps. In this study, three matrices (natural (NR), styrene butadiene (SBR) and rubber) have been tested including recycled component. previously was usi...

Abstract Foamed rubber with a mixed cellular microstructure is compressible material used for various sealing applications in the automotive industry. For technical optimization, sufficiently precise model required. Here description porous elastic and viscoelastic response of low density foamed proposed adapted to ethylene propylene diene monomer (EPDM)-based rubber. The based on spherical shel...

The duality properties of Peti Nets (PN) are exploiled in order to apply an algorithmfor the calculation of colored S-invaiants of Predicate Transition nets (Pr/T nets) to the calculation of the colored T-invariants.
