Properties of Vulcanized Polyisoprene Rubber Composites Filled with Opalized White Tuff and Precipitated Silica
Opalized white tuff (OWT) with 40 μm average particle size and 39.3 m(2)/g specific surface area has been introduced into polyisoprene rubber (NR). Their reinforcing effects were evaluated by comparisons with those from precipitated silica (PSi). The cure characteristic, apparent activation energy of cross-link (E(ac)) and reversion (E(ar)), and mechanical properties of a variety of composites ...
متن کاملPhysical properties of silicone rubber.
2 Mechanical engineer, USAMBRL. 3 Major, Army Medical Specialist Corps, USAMBRL. ROOM-TEMPERATURE-VULCANIZING (RTV) silicone rubber is a versatile material and easy to handle. The ingredients from which it is formed are thick liquids that vulcanize at room temperature within a short period of time after the catalyst is added. Depending upon the relative amounts of solid and foam ingredients, th...
متن کاملEffect of Functionalization of Graphene Nanoplatelets on the Mechanical and Thermal Properties of Silicone Rubber Composites
This study investigated the effect of silane and surfactant treatments of graphene nanoplatelets (GnPs) on the mechanical and thermal properties of silicone rubber (SR) composites. GnPs were modified with aminopropyltriethoxysilane (APTES), vinyltrimethoxysilane (VTMS), and Triton X-100, and then the pristine GnPs and functionalized GnPs were individually incorporated into the SR. Compared with...
متن کاملDielectric Properties of Composites Containing Silicone Rubber and Multiwall Carbon Nanotubes Decorated with Gold
The dielectric permittivity and losses of composites containing silicon rubber and multiwall carbon nanotubes decorated with gold were measured on wide temperature and frequency ranges. The permittivity decreases with increasing temperatures, increases with increasing nanotube mass concentration, and has weak frequency dependence. The losses depend non-uniformly on temperature and frequency.
متن کاملCarbon-silica Dual Phase Filler, a New Generation Reinforcing Agent for Rubber. Part Vi. Time-temperature Superposition of Dynamic Properties of Carbon-silica Dual Phase Filler-filled Vulcanizates
Dynamic properties such as shear modulus, loss modulus, and loss factor were obtained at low strain amplitude over a wide range of frequency and temperature on vulcanizates filled with carbon black, silica, and carbon-silica dual phase filler. The data were shifted along the frequency scale. It was found that instead of a single smooth master curve, a pseudo-master curve with feather-like struc...
