The new issue of RFP is out!
We will take a look at the global automotive markets in 2020 with Ferdinand Dudenhöffer, Director at CAR – Center Automotive Research, at the Italian market for plastics and rubber machinery with Amaplast, and at the 30th International Colloquium Plastics Technology which is going to take place in Aachen, Germany on 11 and 12 March 2020, organized by IKV that is celebrating its 70th anniversary.
Sahbi Aloui (Netzsch) describes Methods for simultaneous dynamic-mechanical and dielectric analysis, Robert Bosch introduces a novel activator for DPG replacement and property improvement, and the article by Katarzyna S. Bandzierz (Lodz University of Technology) and Anke Blume (University of Twente) on the effect of polymer chain modifications on elastomer properties is continued.
In this issue:
- Methods for simultaneous dynamic-mechanical and dielectric analysis – Part 1:
Dielectric investigation of elastomer composites under static deformation
S. Aloui, W. Wurpts, H. Deckmann (Netzsch Gerätebau GmbH)
Electrically conductive fillers can be used as “markers” for condition monitoring of elastomer components, provided the exact correlation between the mechanical and dielectric properties of the material is known. Part 1 of a series of three articles on simultaneous dynamic-mechanical and dielectric analysis, deals with the influence of a defined static mechanical deformation on the dielectric spectra of a carbon black-filled HNBR.
- Novel activator for DPG replacement and property improvement
R. Bosch (Rubber Nano Products (Pty) Ltd)
This paper demonstrates the properties of a novel ionic liquid activator as a DPG replacement and cure additive. The novel activator shows good cure time yet demonstrates scorch safety and some accelerator and zinc efficiency. This paper will focus on the DPG replacement for tyre and conveyor belt segments of rubber manufacturing.
- Effect of polymer chain modifications on elastomer properties – Part 2
A. Blume, L. A. E. M. Reuvekamp, W. K. Dierkes (Department of Elastomer Technology and Engineering, University of Twente), K. S. Bandzierz, D. M. Bielinski (Institute of Polymer and Dye Technology, Lodz University of Technology), J. Dryzek (Institute of Nuclear Physics, Polish Academy of Sciences, Krakow)
Modifications to the polymer chains by curatives, formed by sulfur and fragments of accelerators lead to polymer chain modifications in the elastomers. Emulsion styrene-butadiene rubber (E-SBR) samples, cured with tetramethylthiuram disulfide and sulfur (TMTD/S8), and zinc dialkyldithiophosphate with sulfur (ZDT/S8), were studied. They were characterized in detail in terms of crosslink density and crosslink structures.
