Longitudinal and circular pressure sealing closures were designed and developed for full pressure protective assemblies from a design concept provided by the Aerospace Medical Research Laboratories, invention disclosure number 66/588. This study consisted of (1) designing pressure closure devices, (2) selecting suitable materials for the fabrication of the sealing closure parts and the cylinder...

The objective of this study is to investigate the ability thermoplastic vulcanizates (TPVs) (materials based on PP/EPDM blend) foam under CO 2 batch conditions. EPDM phase, which dispersed into PP was dynamically crosslinked either by a phenolic resin (Resol) or radical peroxide (dicumyl peroxide). results show an influence crosslinking chemistry extensional viscosity TPV. Regarding chemistry, ...

mechanical properties of wood/plastic composites manufactured by polyethylene and polypropylene blends (pp/hdpe) were studied. the sebs (styrene-ethylene butylene-styrene) and epdm (ethylene-propylene diene monomer) were used as compatibilizers to improve the compatibility and miscibility of the interface between hdpe and pp phases. the sawdust and polymers were compounded using an internal mix...

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...

Abstract Rubber blending has been widely used to improve various properties in finished rubber products. The purpose of this paper is investigate the effect filler size, type, concentration, and surface treatment on mechanical, swelling, dielectric, morphology ethylene propylene diene (EPDM)/styrene-butadiene (SBR) blend nanocomposites filled with alumina (Al 2 O 3 ) nanoparticles. Bis-(3-(trie...
