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...

Study of rheological, physico-mechanical and morphological Properties of Nitrile Butadiene Rubber loaded with Organo Bentonite

The rheometric characteristics and physico-mechanical properties of bentonite (Bt)/ and modified bentonite (organo-Bt)/acrylonitrile-butadiene rubber (NBR) were investigated. Scanning electron microscopy (SEM) showed that the rubber chains may be confined within the interparticle space and the Bt particles presented a physical dispersion in NBR matrix. Bt was modified with tetra butyl phosphonium bromide (TBP) in order […] more...

Stress-Strain Curves of BR, NBR and SBR

Synchrotron WAXS Studies of stretched Natural and Synthetic Rubber Networks showing an Upturn in Stress-Strain Curves*

Natural rubber (NR) displays very distinct stress-strain curve with an upturn in the stress at high elongations while most synthetic rubbers do not. This behavior has been associated with strain-induced crystallization. Here we show that three non-crystallizing weak synthetic rubbers, i.e. BR, NBR and SBR, could be reinforced in such a way that their stress-strain […] more...

Schwingungsfortsetzung und Dämpfung in Elastomer – Stahlgrenzflächen von Federn

A rubber-buffer-pendulum and an impulse-hammer-pendulum are bulit to investigate damping and isolation properites of different rubber-buffers. It can be summarized that soft rubber-buffers show the best isolation and damping properties. Hard rubber-buffers show the largest mechanical impedance and thereby are most resistant against mechanical loading. Hard rubber-buffers show poor damping and isolation properties. Therefore there […] more...
