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.

Bei der Auslegung von Silikonbauteilen im Automotive-Bereich ist es wichtig, das mechanische Verhalten unter Zug-, Druck- oder Kombinationsbelastung vorherzusagen. In der Arbeit wird die Kompressibilität bzw. das Kompressionsmodul des Materials mittels eines volumetrischen Kompressionsversuchs untersucht.

Two-roll mill laboratories mixer were used to prepare EPDM composites based on EPDM/GR blend loaded with different content of waste iron powder (WIP). A notable decrease of tensile strength upon reaching 50 phr WIP is noticed. Filler agglomerates at higher WIP content (detected by SEM) leads to mechanical properties' failure.

Polyisoprene (IR) and polybutadiene (BR) rubber with narrow molecular weight distribution are used to investigate the influence of chain length on blend behavior. For this purpose, dynamic-mechanical analysis and broadband dielectric relaxation spectroscopy are used. Blending BR and IR results in a homogeneous miscible system. 

Carbon black surface chemistry was modified by treatment with benzyl triethyl ammonium chloride (BTEAC) and effects of the same were studied in styrene butadiene rubber and butadiene rubber-based compound. The functionalized carbon black showed improvement in filler dispersion and reduction of filler-filler interaction.

The aim of the present work was the spatial characterization of potential inhomogeneities in epoxidized NR (e-NR) / solution SBR (s-SBR) rubber blends caused by crosslinking. In addition to micro-indentation and atomic force microscopy (AFM), the investigated samples were also characterized by TEM, DSC and physical testing methods.

In a research project, the single-stage coextrusion of EPDM and PE-LD was realised. A novel coextrusion die was designed rheologically and thermally. During the co-extrusion trials, the die temperature and the screw speed were varied. Subsequently, the rubber was vulcanised by microwave and infrared radiation, which could easily be stopped from heating up the thermoplastic. 

The present work investigates the effect of blending polyester (PET) and polyamide (PA) by carbon fibers (CF) in the form of simple weaves and sliding on cotton textile. It was revealed that electrostatic charge (ESC) decreased with increasing CF content. besides, after sliding ESC displayed higher values than that observed after contact-separation.
