Over the last several years, the trend in the marketplace for molded silicone rubber parts has been toward the use of liquid silicone rubber (LSR) due to its ease of processability, design versatility, excellent quality, and productivity gains. Fluoromethyl co-polymer LSR’s were introduced which offered intermediate fuel and solvent resistance; however, in very harsh environments, […] mehr...
The friction coefficient of rubber sliding against polymeric indoor flooring materials of different surface roughness was investigated under the following conditions: dry, water, water and soap, oil, water and oil It was found that, at dry sliding, the friction coefficient decreased with increasing surface roughness and applied load. At water lubricated sliding, the friction coefficient […] mehr...
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...
Es wirde eine neue Generation von Salzbadanlagen zum Vulkanisieren von Gummiprofilen vorgestellt. Hohe Wirtschaftlichkeit in Verbindung mit der erforderlichen Umwelttechnologie gestaltet die Salzbadtechnologie ausgesprochen attraktiv. Durch das Rückgewinnungssystem wird der Salzverbrauch auf ein Minimum reduziert. Das Zusammenwirken der einzelnen Anlagenkomponenten erlaubt Durchlaufgeschwindigkeiten von 60 bis 100 m/min und setzt neue Dimensionen bei der Kostenreduzierung von […] 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...

Eine etwa 98%ige Transparenz in Kombination mit den für additionsvernetzende Flüssigsilikonkautschuke (LSR) typischen Produktivitätsvorteilen macht die LSR7000-Serie von Momentive zu einem interessanten Konstruktionswerkstoff 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...
The technological properties of raw natural rubber (NR) from new rubber tree clones of IAC series (40, 56, 300-303) and RRIM 600 (asiatic reference clone) were evaluated by: acetone extract (%), Wallace plasticity (P0), plasticity retention index PRI (%) and Mooney viscosity (VR). There were significant variations (P ???? 0.01) between clones and tappings for […] mehr...
The structure of branch-points in natural rubber (NR) was studied by structural analysis after washing of fresh and aged NR latices with centrifugation three times in the presence of sodium dodecyl sulphate (SDS). The nitrogen content of rubber from aged latex (HG-NR) and fresh latex (LG-NR) decreased to 0.02 % after three times centrifugation, which […] mehr...
