In-situ Testing of Bonded Polymer Joints by means of Computed Tomography
The mechanical behavior of bonded PEEK joints was investigated in-situ by means of computed tomography. From the data, the multi-axial strain distribution was analyzed for a tensile shear test of the entire adhesive joint as well as locally in the adhesive layer.Weiterlesen...
Free-Volume Changes in EVA Composites Studied by Positron Annihilation Lifetime Technique
The influence of different concentrations (0 – 60 wt %) of carbon black (HAF) filler on macrostructure and microstructure of ethylene vinyl acetate (EVA) composites was studied through electrical, mechanical measurements and positron annihilation lifetime (PAL) spectroscopy. The electrical conductivity measurements showed an abrupt increase when the concentration of HAF reaches 30 wt%.Weiterlesen...
Influence of Silica-Polymer Bond Microstructure on Tire-Performance Indicators
Changes in the coupling agent structure in a silica-silane filler system lead to alterations of the microstructure of the silica-polymer interface and determine the dynamic properties, thus wet skid resistance (WSR) and rolling resistance (RR) of a tire tread.Weiterlesen...
Preparation of Super-low Protein Natural Rubber
An attempt was made to remove all proteins from natural rubber in the latex stage by both denaturation of the proteins and removal of lipids, which provided free space between them for fast detachment of the proteins. The removal of proteins was carried out by incubation of natural rubber latex with surfactant, denaturing agent and polar organic solvent, followed by centrifugation.Weiterlesen...
Method for computerized Estimation of Temperature Profiles for Elastomers
In this work a study was carried out about the influence of temperature on the transmission characteristics and lifecycle of an elastomer based on natural rubber. The resulting experimental data were used to develop a thermo-viscoelastic material model, which was then integrated into a new concept for temperature-dependent lifecycle analysis.Weiterlesen...

Lotte Versalis Elastomers to build SIS/SBS plant in South Korea
Italian elastomers producer Versalis (Eni), San Donato, and South Korean petrochemical company Lotte Chemical, Seoul, are extending their cooperation in the elastomers business under a technology license agreement regarding, in particular, the Styrene-Isoprene-Styrene and Styrene-Butadiene-Styrene (SIS/SBS) product lines.Weiterlesen...
Zeon plans to build and to shut down rubber factories
Zeon, a Japanese maker of synthetic rubbers and high-function materials headquartered in Tokyo, will double its capacity in Singapore for solution-polymerized styrene-butadiene rubber (S-SBR), reports Nikkei Asian Review. Furthermore, the company itself annouced it is set to close the synthetic rubber plant in Wales, UK.Weiterlesen...
