Welche Dichtungsmaterialien sind für Wasserstoff geeignet?
Wasserstoff als Energieträger nimmt bei der Energiewende eine Schlüsselfunktion ein. Das Fraunhofer LBF will mit Industriepartnern Dichtungsmaterialien erforschen, die für den Transport von Wasserstoff geeignet sind.Weiterlesen...
Adhesion Improvement between Natural Rubber and Ethylene Methylacrylate Copolymer by Surface Chlorination
FT-IR spectra showed the presence of chlorine group on modified surface, while roughness and stiffness increased gradually with chlorination time.Weiterlesen...
Metal Ions Adsorption by RAFT-modified Cellulose
Water has a wide impact on all aspects of human life like health, food, energy and economics. In the last decades, many methods have been studied for treatment of underground water like; ion exchange, chemical precipitation, nano-filtration, reverse osmosis and adsorption.Weiterlesen...
Activation Energy of thermal Degradation of Tetrafluoroethylene-Propylene Elastomer
The longer the pre-aging time, the more the linearity of the analyzed line with reference to ISO 11358-2 was improved. The activation energy of the sample aged 240 h was from 159 kJ/mol to 164 kJ/mol, which was depending on the weight retained. The value obtained with reference to ISO 11358-3 was from 149 kJ/mol to 159 kJ/mol.Weiterlesen...
Influence of Fe2O3 Nanoparticles and Glass Fiber on the Compressive Properties of Epoxy Composite
The aim of this work is to study the influence of Fe2O3 nanoparticles and glass fiber concentrations on the compressive properties of epoxy composites. Fe2O3 nanoparticles and glass fiber are added to epoxy phase in concentrations of 0.2, 0.4, 0.6 and 0.8 wt. %.Weiterlesen...
Effects of short Fibers in thermoplastic Elastomers
The crucial advantages of Thermoplastic Elastomers (TPE) are that they have rubber elastic features but they have not to be irreversibly vulcanized like rubber.Weiterlesen...
Wie Kohlenstoff aus Luft gewonnen wird
Das Karlsruher Institut für Technologie (KIT) demonstriert mit dem NECOC-Verfahren, wie CO₂ aus der Atmosphäre entnommen und durch kombinierte Prozesse in einen stabilen Kohlenstoff umgewandelt werden kann.Weiterlesen...
Friction and Wear Displayed by the Scratch of Epoxy filled by recycled Rubber Particles
The application of floor materials made of epoxy resins is limited due to their brittleness. Paraffin oil and recycled rubber particles were added to epoxy.Weiterlesen...
Industrial Benchmark PU-Foams with expandable Graphite/P-Flame Retardant Combinations
Polyurethane foams (PUF) are generally flammable, so they are limited in some applications due to strict fire safety requirements. In this study, three distinct industrial benchmark polyurethane foams containing synergistic combinations of expandable graphite (EG) and phosphorous flame retardants (P-FR) were investigated one by one for their fire performance and smoke behavior.Weiterlesen...
Die K als Schaufenster der Branche
Die K war für die Kautschukbranche gleich das zweite Großereignis im Jahr 2022. Ende Juni fand bereits in Nürnberg die Deutsche Kautschuktagung (DKT) statt. Doch die Unternehmen hatten zur K weitere Neuentwicklungen zu präsentieren.Weiterlesen...
