the blending of nr and br rubber blend with n330 carbon black is studied on curing behavior and the physico-mechanical properties of a sbr rubber based tire tread compound containing n234 carbon black. the effect of sulphur and accelerator contents on different properties of rubber compound is also tested with a wide range of curing agents. partial substitution of sbr with nr shows significant ...

OBJECTIVES This study evaluated the mortality experience of workers from the styrene-butadiene rubber industry. Concerns about a possible association of 1,3-butadiene and styrene with lymphohaematopoietic, gastrointestinal, and lung cancers prompted the investigation. METHODS A retrospective follow up study was conducted of 15,649 men employed for at least one year at any of eight North Ameri...

Cellulose nanofibers (CNFs) are bio-sourced nanomaterials, which, after proper chemical modification, exhibit a unique ability to disperse carbon-rich micro- and nanomaterials can be used in the design of mechanically strong functional nanocomposites. When preparation graphite anodes for Li-ion batteries, they have potential outperform conventional binders such as carboxymethyl cellulose (CMC) ...

This article evaluates the impact of different fiber types on flexural creep self-compacting concretes (SCC). The study focuses effects vegetable fibers (Hemp, [H] and Dis [D]) synthetic (Polypropylene [P]) SCC. To assess SCC, various tests such as spreading, J Ring, compressive strength, strength are conducted. authors developed a test configuration methodology to subject beams measuring 120 c...

this paper deals with the interfacial effects of silica fume (sf) and styrene-butadiene polymer (sbr) on compressive strength of concrete. analyzing the compressive strength results of 32 concrete mixes performed over two water-binder ratios (0.35, 0.45), four percentages replacement of silica fume (0%, 5%, 7.5%, 10%) and four percentages of sbr (0%, 5%, 10%, 15%) were investigated. a mathemati...

• Photo-actuation behavior was detected in the vulcanized rubber for first time. styrene-butadiene (SBR) composites filled with graphene nanoplatelets (GnPs) were investigated. ionic liquids significantly enhanced photo-actuation behavior. The effects of butylpyridinium bromide-based (ILs) on vulcanization kinetics, mechanical properties and ability Two different ILs, 1-butylpyridinium bromide ...

Employing computer simulation to accurately and quantitatively predict the mechanical properties of polymeric materials is a long-standing challenge. Herein, we consider two methods simulate based on fully atomistic model crosslinked styrene-butadiene rubber (SBR) network via molecular dynamics simulation. In first method (stepwise deformation relaxation), by keeping tensile velocity constant r...

1,3-Butadiene, a high-production volume chemical used largely in the manufacture of synthetic rubber, is a multiple organ carcinogen in rats and mice. In inhalation studies conducted in mice by the National Toxicology Program, high rates of early lethal lymphomas occurring at exposure levels of 625 ppm or higher reduced the development and expression of later developing tumors at other sites. U...

This study has been initiated to quantify the release of the Polycyclic Aromatic Hydrocarbon (PAH) species from Styrene· Butadiene Copolymer (SBR) during gasification. The identification and quantification has been detennined experimentally using Gas Chromatography/ Mass Spectroscopy (GC/ MS) coupled to a Thenno-Gravimetric Analysis (TGA) unit. SBR samples were pyrolysed in a TGA unit in a Nz a...
