In the present study „Application of recovered Carbon Black (rCB) from End-ofLife Tire pyrolysis in butyl rubber compounds“, the research on the use of rCB in new butyl compounds is presented. In general, pyrolysis of scrap tires is considered a future-oriented additional technology regarding the lack of recycling capacities.

Hydrogenated styrene butadiene rubber (HSBR) produced by hydrogenating a styrene butadiene rubber (SBR). Compared to conventional SBR, HSBR offers several advantages, such as increased strength, toughness, and resistance to heat, aging, and chemicals

Im Gegensatz zum untersuchten Einfluss verschiedener Metalloxid-Pigmente auf die thermischen Eigenschaften einer peroxidisch vernetzenden FKM-Mischung (1. Teil, KGK 05/24) wird hier der Einfluss eines zunehmenden Weichmachergehaltes auf die Kinetik der chemischen Vernetzungsreaktion, auf die Temperaturleitfähigkeit, die spezifische Wärmekapazität, die Wärmeleitfähigkeit und die Wärmeeindringzahl betrachtet.

This study investigates the mechanical, physical, and wear-resistant properties of different epoxy composites. An epoxy matrix is used as the base material, while a combination of rocca natural oil and TiO2 nanoparticles is used as filler. The experiments include XRD analysis, hardness measurements, stressstrain curve analysis, friction coefficient and wear rate calculations and topography examination of worn surfaces using optical 3D and SEM imaging.

Die Ausprägung des nichtisothermen GJ-Effektes wird entscheidend von dem erzielten Ausmaß der Entropieverringerung bei der Deformation eines elastomeren Profils bestimmt. Aber auch die thermischen Eigenschaften des Elastomerwerkstoffes beeinflussen mit, inwieweit eine aufrechterhaltene Entropieverringerung bei Wärmezuführung durch einen Spannungszuwachs sichtbar wird. 

Femur fractures, often resulting from trauma or osteoporosis, pose significant challenges due to their impact on mobility and quality of life. Metallic implants like titanium and stainless steel, despite their strength and biocompatibility, present issues related to stress shielding, altered biomechanics, and limitations in diagnostic imaging.

Over the last three decades, the Rubber Process Analyzer has evolved as the processability test instrument of choice for measuring and solving many rubber factory problems. Also, a new ASTM reflective microscope method is also commonly used.

Biodegradable and environmentally friendly polymers made from renewable raw materials are now the preferred choice for a wide range of applications. However, a combination of petroleum and bio-based sources is now being studied for developing cost-effective and environmentally friendly rubber products, with a specific pursuit of the European Green Deal.

This study aimed to identify the effect of temperature and co-agent type on the stress softening, energy dissipation, and damping properties of phenyl-methyl-polysiloxane (PVMQ) elastomers prepared with a peroxide curing system. We identified that temperature and type of the co-agent are two critical parameters controlling the damping properties of polymers and a decrease in temperature decrease of the damping capacity of silicone elastomer

Mittels Dynamisch-Mechanischer-Analyse (DMA), d.h. über eine statische Versuchsführung und nichtisothermer Vorgehensweise, wird die indirekte Bestimmung von Entropieverringerungen in Abhängigkeit des Deformationsgradienten des elastomeren Probenkörpers vorgestellt. Ein relativ einfacher, mathematischer Modellansatz erlaubt die Berechnung von Entropieverringerungen aus den Messwerten.
