Natural rubber (NR) and cyclized NR (C-NR) containing 5, 20, and 90 % degree of cyclization were blended by dynamic vulcanization in a high shear environment using sulfur based curing systems at 160 °C. In addition, the addition of sulfur compound in C-NR (90 %) latex before vulcanization process was also studied. As expected, all […] mehr...

The present work discusses the effect of surface roughness of ceramic plates on the friction coefficient of sliding rubber and leather. The test results showed that, the friction coefficient decreased to a minimum value then increased with increasing the surface roughness of the ceramic surface. The friction coefficient as a function of the surface roughness […] mehr...

This paper presents the results of studies to achieve adequate steel cord adhesion whilst seeking to improve hysteresis characteristics and to reduce compound heat generation through the use of chemically activated aramid fibers called Sulfron 3001. This unique ingredient is capable of reducing the compound hysteresis significantly. This reduction of hysteresis translates into lower heat […] mehr...

The effect of silica and its surface chemical modification by silane (Si69) on the dynamic-mechanical properties of solution styrene-butadiene rubber (S-SBR) was investigated. Dynamicmechanical measurements were done to evaluate both the real and imaginary parts of the shear compliance over a wide range of frequency and temperature, 10-4 to 100 Hz and -50 to 120 […] mehr...

A good distribution of fillers and elastomers in a compound is a challenging task, as these components greatly differ in polarity. One possibility to overcome the polarity differences between fillers and polymers is to adjust the surface properties of the filler by plasma polymerization: A proper choice of the monomer and the process parameters allows […] mehr...
