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...

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...

PP/EPDM Thermoplastic Vulcanizate (TPV) filled with carbon black (CB) has been prepared and the localization of filler in blend was observed to be dependent on crosslinking chemistry: rubber phase when EPDM crosslinked phenolic resin (resol) at interface dicumyl peroxide (DCP). It proved, based model reactions that mimicked what could happen during process high temperature, DCP led polymer chai...
