Scrap tires – the new recycled construction material

Innovation for Road Construction

Autoreifen gehören auf die Straße? Stimmt schon. Aber seit rund zwei Jahrzehnten finden sie sich auch immer häufiger in der Straße. Möglich wird das durch recycelte Altreifen und ein Prozesshilfsmittel. Das Additiv ermöglicht, Gummimehl aus Altreifen zu einem gummihaltigen Asphalt zu verarbeiten. more...

Investigation of Tire Model Compounds

Optimizing the stress-strain behavior of hybrid yarns in elastomer components

Using a tire model compound, the bimodular stress-strain behavior of aramid/PA hybrid yarns in the range of 1-10% strain was adjusted by varying the process parameters during the hybrid yarn production, different yarn constructions, coating of the hybrid yarns and modifying the elastomer matrix by additives. more...

Tailor made Silica/Silane-Systems

Precipitated Silica – Morphology Control

Precipitated silica, especially in combination with bifunctional organosilanes, is one of the most important active filler, filler system respectively, that is used in the rubber industry and especially in passenger car tire tread compounds. Despite the fact that there are already many different silica having a broad range of different specific surface areas, the variety of cluster sizes in the nanometer range is rather low in contrast to the broad range of available carbon black structure variations. more...

Abrasion Resistance

Improving the mechanical Properties of Tyre Tread Compounds with different Types of Carbon Fibers

The properties of unsized and coated with different sizing material carbon fiber (CF) reinforced tyre compounds were examined. Unsized CF and CFs which were sized with polyurethane-, epoxy- and phenoxy-sizing were selected. A blend of SBR and BR was used as matrix. The tyre compounds were prepared by using open two-roll mill. The effects of […] more...

Rolling Resistance of TBR Tires

NR-Silica-Masterbatches – The easy Processing Way to High Quality Compounds

Growing requirements of higher fuel economy increase the pressure on producers of TBR tires to use silica as a filler in Natural Rubber compounds. Currently this seems to be the silver bullet to further reduce Rolling Resistance without compromise in Skid and Wear. High quality Natural Rubber compounds filled with Silica and Silane in high […] more...

Anspruchsvolle Rezepturen erfordern eine hochentwickelte Mischtechnik

Das Tandemverfahren revolutioniert die Reifenindustrie

Die Anforderungen an Reifenmischungen steigen und ab 2020 soll der Kraftstoffverbrauch nochmals um 20 Prozent sinken. Dafür notwendig sind komplexe Kautschukrezepturen für Reifen, in denen wahrscheinlich flüssige Polymere, neue Füllstofftypen und sonstige Zusatzstoffe eine wichtige Rolle spielen. Schon jetzt hat das Tandemverfahren den Mischprozess erheblich verbessert. In Zukunft müssen die Maschinen bezüglich Dispersion, Distribution, Temperaturkontrolle und Prozesskonstanz bei verbesserter Wirtschaftlichkeit weiter optimiert werden. more...

EPDM blend for Profiles

Elaboration of Rubber Profiles for Automotive-industry

EPDM is extensively used in automotive applications and is favored to superior heat resistance, ozone resistance and weathering resistance. This study aims to elaborate rubber profiles for car windows and doors based on EPDM and EPDM/LLDPE blend formulations. Different prepared rubber compounds and vulcanizates were evaluated by determining the rheometric characteristics and physico-mechanical properties. The […] more...

Oscillatory rheometer measurements

Characterization of Summer Tire Tread Compounds by Large Amplitude Oscillating Shear (Laos)

In the last years, characterisation of polymers by Fourier analysis of Large Amplitude Oscillating Shear (LAOS) signals became a powerful, widely spread technique. Oscillatory rheometer measurements were carried out in the non-linear viscoelastic domain for summer tire tread compounds based on the “green tire recipe”. Compound variations were realized by changing the polymer base well […] more...
