Vulcanization of silica-filled car tread compounds

Rhenocure DR – A New Secondary Accelerator for Rubber

Diphenyl guanidine (DPG) is the most used secondary accelerator in silica filled passenger car tread compounds Beside its function as secondary accelerator DPG acts in this application also as a processing aid. A problem accompanied with DPG is that it releases carcinogenic aniline during the vulcanization process. Several solutions are available to replace DPG like […] more...

Tribology of CNT filled Epoxy

Tribological Behavior of Epoxy Reinforced with Carbon Nanotubes and filled by Vegetables Oils

The influence of reinforcing epoxy by carbon nanotubes (CNT) and filling by different types of vegetables oils (olive, corn, sunflower, sesame, almond and paraffin oil) on the friction coefficient (µ) and wear resistance is investigated. CNTs of 0.25, 0.5, 0.75 and 1 wt. % content have been added to epoxy matrix mixed by 10 wt. […] more...

Rice Husk Powder in Rubber

Effects of carburized Rice Husk Powders on physical Properties of Elastomer based Materials

In this study the effects of carburized rice husk (CRH) powders on the mechanical properties of SBR (SBR 1502) / waste rubber type elastomer based materials were investigated. In addition to the calcite and rubber powder fillings in the general composition of a rubber formula used in footwear production, CRH obtained by the Proliz method […] more...

Understanding the Behavior of the Coupling Agents TESPT and SI 363 in short-cut Aramid Fibre reinforced Elastomers

In this study the coupling agents Bis-(triethoxysilylpropyl) tetrasulfide (TESPT) and mercaptopropyl-mono-ethoxypolyether-silane (Si 363) are compared to each other in a standard SBR formulation for adhesion-activated epoxy-coated short-cut aramid fibres. Comparing TESPT with Si 363 with the help of a design of experiments approach gives a better understanding of the relevant factors, in order to judge […] more...

Magnetic and dielectric Properties

PMMA Nanocomposites based on Laser fragmented Fe3O4 Nanoparticles

Laser photo fragmentation technique has been utilized as a versatile method to produce magnetite (Fe3O4) nanoparticles. It was found that, the diode laser beam with wavelength 808 nm is the most effective one, as it reduces the particle size of Fe3O4 to 5.5-26 nm. Casting technique was used to prepare nanocomposites based on polymethyl methacrylate […] 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...

Magneto-Active Elastomers: Effect of the Particle Dispersion on the Switching Ability

As magneto-active elastomers rubber composites based on highly elastic polymer matrix filled with magnetic barium ferrite (BaFe12O19) particles were investigated. Due to the high ratio of surface to volume and magnetization are magnetic particles prone to aggregate. To enhance the dispersion and the compatibility between the particle and the rubber matrix a functionalization of the […] more...
