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...

Practical adhesion of rubber to aluminum is measured for various aluminum silanization treatments. In this study, 6-(3-triethoxysilylpropylamino)-1,3,5-triazine-2,4-dithiol (TES) was used as the coupling agent for preparing self-assembly monolayers (SAMs) on an aluminum surface. The structure and chemical composition of the SAMs were analyzed using Fourier transform infra-red spectroscopy (FT-I...

Polymeric insulators are widely used in newly constructed systems and to replace porcelain and glass insulators in existing power lines due to its improved performance. This paper presents an experimental work, which was carried to evaluate the flashover voltage (kV) of Silicone rubber / Ethylene propylene diene monoemer blends of outdoor insulators. Effect of environmental parameters at desert...
