Carbon black–polymer interaction: A measure of reinforcement

Abstract: The interaction of carbon blacks with high polymers during the mixing process was studied by using fillers having a wide range of surface characteristics. Glass beads, Graphon, high-structure blacks, and heat-treated blacks were mixed with elastomers in the Brabender Plasticorder. With the use as a rubber matrix of a high polymer that did not materially change during the mixing process in molecular weight or viscosity, excellent correlation was found between final torque required for mixing and black structure and between peak torque and bound rubber. Increasing interaction was shown to lead to increased mixing torque, increased Mooney viscosity, increased modulus, and higher state of cure, as measured by swelling. If the high polymer matrix breaks down during the mixing process these influences of interaction are mostly obscured by diminishing molecular weight.

Carbon blacks and rubber compositions containing the carbon blacks

Abstract: Carbon blacks having a N 2 SA of from at least about 150 m 2 /g to about 180 m 2 /g, a DBP of about 125 cc/100 g or less, a Dmode of 70 nm or less, a N 2 SA/I 2 No. ratio of 0.85 to 0.98 and a ΔDBP less than 210 cc/100 g which, when incorporated into rubber compositions, impart increased abrasion resistance, heterogenous abrasion resistance and grip performance properties. Also disclosed are rubber composition incorporating the novel carbon blacks.

Ink compositions containing metal oxides

Abstract: An ink composition is disclosed which comprises at least one ink vehicle, at least one colorant and at least one metal oxide. The colorant may be a dye or a pigment, or both, and the colorant is non-reactive with the metal oxide in the ink vehicle. Also disclosed are inkjet formulations using the above-described compositions and methods of improving such properties as optical density.

Architectural membrane structures and methods for producing them

Abstract: An architectural membrane structure preferably includes an aerogel material disposed, for example, between two outer layers. The aerogel can be in monolithic or granular form or can be present in an aerogel composite. A method for manufacturing an architectural membrane structure includes securing an insert, e.g., an aerogel blanket, composite or granular aerogel, between a first and second layer. The architectural membrane structure can be used as a tensioned panel in envelopes such as roofing, overhangs, canopies or in other architectural or structural fabric applications.
