The filler dispersion state, filler aspect ratio and compatibility between filler and rubber have a significant influence on the thickness of the immobilized polymer layer [28]. Since the same kind of filler was used for all of the SBR nanocomposites, the influence of filler aspect ratio can be ignored.
Carbon nanotubes (CNTs) hold the promise of delivering exceptional mechanical properties and multifunctional characteristics. Everincreasing interest in applying CNTs in many different fields has led to continued efforts to develop dispersion and
The effect of the blending ratio of a polyurethane matrix and oilpalm empty fruit bunch (EFB) fibers on the mechanical properties of biocomposite boards has been studied. The PU matrix and EFB fibers were used at blending ratios of 25:75, 30:70 and

Jan 14, 2016· The process of preparing fillers incorporated master batch involves preparation of the individual filler dispersions by mixing each filler with surfactants. Further fresh rubber latex is soap sensitized by mixing it with surfactant. The filler dispersions are added to the soap sensitized rubber latex slowly under stirring to form the master mix.
Dispersion processing—the generation of particulate forms of polymers and their conversion into products—is a key technique that is likely to grow in importance, driven by both environmental and materials considerations. The polymer may be in the form of a dry powder, an aqueous dispersion (, a latex), or a nonaqueous dispersion (NAD).
Styrenebutadiene or styrenebutadiene rubber (SBR) describe families of synthetic rubbers derived from styrene and butadiene (the version developed by Goodyear is called Neolite).These materials have good abrasion resistance and good aging stability when protected by additives. In 2012, more than million tonnes of SBR were processed worldwide. About 50% of car tires are made from various ...
It is well known that the filler dispersion and filler–rubber interaction are two critical factors, which determine the performance of the composites [1, 22]. Other factors are structure, size, shape, surface area and surface reactivity of the filler particles [22, 23, 24]. Titanium dioxide is widely used as filler in polymer matrix composites.

Sep 23, 2009· After dispersion of the prepolymer in water and subsequent chain extension, the monomers can be polymerized, thus giving a high Mw urethane acrylic hybrid dispersion. When comparing these hybrids with the blend of a cosolventfree urethane and an acrylic dispersion, it appears that much stronger films result from the hybrid particles.
