In this issue:
- The current and future market for thermoplastic elastomers in automotive applications
P. Ellis (Smithers Rapra)
The global market for thermoplastic elastomers (TPE) in automotive applications is with few exceptions, growing faster than any other elastomer. It is estimated to be 1.97 million t in 2019. This is forecast to rise to 2.86 million t by 2024, with a compound average growth rate (CAGR) of 6.6 % over the period 2019 to 2024. This CAGR is slightly above the 6.2 % GAGR for the total global thermoplastic elastomers’ market. The following article will have a closer look at the reasons of growth.
- LSR foam produced by injection molding
R.-U. Giesen, M. Hartung, S. Marl, H.-P. Heim (Institute for Materials Technology, Department Polymer Technology at University of Kassel)
This paper illustrates the effect of expandable thermoplastic microspheres as blowing agents in liquid silicone rubber (LSR). They can significantly reduce the density of the vulcanizates and thus lead to material savings in the application and positively influence the insulation behavior against heat and cold as well as the floatability.
- Effect of polymer chain modifications on elastomer properties – Part 1
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.
- Stability and continuity. New VDI guideline 2017 Medical Grade Plastics defines requirements for plastics in medical, diagnostics and pharmaceutical packaging
S. Roth (Schmalkalden University of Applied Sciences)
Safety for patient and user is an essential requirement for medical products, in-vitro diagnostics and pharmaceutical packaging. Subsequently, plastics grades used in medical have to fulfil particular requirements, i.e. constant properties, formulation lock or biocompatibility. Surprisingly, no standard has existed to define the requirements for medical grades so far.
