Use of aerogels for deadening structure-borne and/or impact sounds

Abstract: Aerogel particles, in particular in the form of composite materials, are used to deaden structure-borne and/or impact sounds.

Carbon—Silica Dual Phase Filler: Part III. ESCA and IR Characterization

Abstract: A series of carbon—silica dual phase fillers have been analyzed using electron spectroscopy for chemical analysis (ESCA) and infrared spectroscopy (IR). These techniques reveal that the silicon in these materials is consistent with that in silica, and the predominant carbon in the carbon phase is similar to the predominant carbon in carbon black. ESCA and IR experiments demonstrate that the carbon—silica dual phase fillers are comprised of composite aggregates, each containing carbon and silica phases. In these dual phase aggregates the silica phase is intimately distributed with the carbon phase. Quantitative ESCA reveals that these dual phase fillers have excess oxygen over the expected stoichiometric amount for the silica present. This excess oxygen is likely due to oxygen groups on the carbon phase. Analysis of the ESCA oxygen Auger lines in combination with various chemical treatments substantiate the presence of carbon phase oxygen groups on the dual phase fillers. Quantitative ESCA in comb...

Polymer foam containing chemically modified carbonaceous filler

Abstract: Polymer foam compositions comprise polymer foam and chemically modified carbonaceous filler, specifically, carbonaceous filler having polymer moieties chemically bonded to the carbonaceous particulates. Exemplary carbonaceous fillers include carbon black, activated carbon, graphite, carbon fibers, fibrils and the like. The polymer moieties have a valence orbital bond to the carbonaceous particulate, such as an ionic or covalent bond. The chemical bond survives shear forces and the like, such as would be encountered by filler material in a reaction injection molding process for the manufacture of filled polyurethane foam insulation panels.

Method for producing carbon black

Abstract: A process for producing carbon blacks having lower surface area and structure wherein steam is introduced into the combustion gas stream at a point located a distance “L” from the point of introduction of feedstock into the combustion gas stream such that the ratio L/D ranges from 0 to less than 1.0, where “D” is the diameter of the zone of the reactor at the point of introduction of feedstock.
