Thermoplastic elastomers (TPEs) are provided with many properties of elastomeric or rubbery materials, but can be processed with the thermoplastic processing methods; they are one of the fastest growing polymers materials which combine the elastic and mechanical properties of crosslinked rubbers with the melt processability of thermoplastics. In addition, TPEs find a lot of applications in auto...

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...

Low-temperature reactive mixing of controlled electron beam modified Polytetrafluoroethylene (PTFE) nanopowder with Ethylene-Propylene-Diene-Monomer (EPDM) rubber produced PTFE coupled EPDM rubber compounds with desired physical properties. The radiation-induced chemical alterations in PTFE nanopowder, determined by electron spin resonance (ESR) and Fourier transform infrared (FTIR) spectroscop...

Abstract In response to the continuous demand for industry progress and need low-cost alternative materials that have superior properties than present ones, a new coupling agent was used treat composites, which were as backing in ultrasonic array transducers. transducers, back-echo reverberation piezoelectric elements occurs, so are critical reducing these echoes. The Cu–Al–Zn-alloy treated wit...

The effect of nanoclay in combination with other inter fillers in ethylene propylene diene monomer (EPDM) rubber vulcanizate were studied. Curing characteristics were carried out using rubber process analyzer (RPA). Mechanical, thermal and morphology characterization of EPDM nanoclay composites were studied.

INTRODUCTION Polytetrafluoroethylene (PTFE), a highly crystalline polymer with melting temperature around 330°C, possesses unique properties. Chemically inert, it has high chemical and heat resistance with upper service temperature around 260°C. Since its invention it has found limited applications especially as an additive because of its high molecular weight and inert surface. However, by mid...

of Research 1. Evaluation of BBM BBM of the flight hardware was evaluated by repeated culture experiment under the simulated conditions for space experiment. As a part of device development, materials of a fixed container (an EPDM bag) and the fixation ability of the fixatives were also evaluated. After long term storage (> one month) in the EPDM bag gave little damage on the fixed specimens wh...

Melt free-radical grafting reactions between ethylene-propylene-dieneterpolymer (EPDM) and glycidyl methacrylate (GMA) were investigated in a batch mixer (170°C, 60rpm). Effect of dicumylperoxide (DCP) initiator and GMA functionalizing monomer concentrations was studied on the grafted EPDM characteristics. Titration results indicated an increase in the graft degree (GD) and gel content (GC) val...
