TPE Magazine 04/2019 now available!

Enjoy reading insights of TPE expert Patrick Ellis on the current and future market for thermoplastic elastomers in automotive applications and have a look at our special on additive manufacturing with soft materials. Arburg talks about the latest update of the Freeformer and what this famous machine can do in the field of 3D printing of TPEs.

Richard Spontak and his team from the North Carolina State University describe strategic pathways for the future of broad-spectrum anti-infective TPE materials. Bonding is always a key property when processing TPEs. Prof. Moritzer and his team from the University of Paderborn/Germany, examine the question of bond strength of TPU to cast polyurethane which is interesting for a variety of industrial applications.

  • 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.
  • Investigation of the bond strength between injection moulded TPU and a reactive, castable polyurethane mass – Applications, processing and determination of bond strengths
    E. Moritzer, J. Jilg (Kunststofftechnik Paderborn (KTP) – University of Paderborn) and N. Sibbe (Gustav Meister GmbH)
    Polyurethanes are one of the most versatile material groups within the plastics processing industry. Their fields of application can be found in a large number of technical and everyday products. A special niche application, which has been available on the market for a long time, is two-component plastic screens, which combine thermoplastic polyurethanes (TPU) with reactive and castable polyurethane compounds (2C-PU system). The TPU screen inserts have the function of classifying and dewatering the sieved material, while the PU mass serves as composite and carrier material. Compared to other soft plastics from the thermoplastic elastomer (TPE) segment, polyurethanes have a particularly high resistance to abrasive media in the recycling, natural stone, chemical and wood processing industries, which is why they are primarily used in plastic screens. In order to quantify the bond between these two soft components (TPU/PU), this paper shows the development of a manufacturing and testing system, since there is no suitable test guideline available for a soft-soft 2C bond.
  • Antimicrobial thermoplastic elastomers – Strategic pathways for the future of broad-spectrum anti-infective materials
    B. S. T. Peddinti, F. Scholle, R. A. Ghiladi, R. J. Spontak (Departments of Chemical & Biomolecular ­Engineering, Biological Sciences, Chemistry, and ­Materials Science & Engineering, North Carolina State University)
    As the need for next-generation self-sterilizing materials escalates to combat the growing global threat of various microbes, especially those that exhibit drug resistance or the capability thereof, new material design paradigms must be developed to promote antimicrobial measures without sacrificing environmental integrity. In this work, the antimicrobial properties of two chemically different systems of thermoplastic elastomers (TPEs) are examined. Two strategies are considered: antimicrobial photodynamic inactivation (aPDI) and antimicrobial anionic inactivation (aAI). It is demonstrated that both strategies are effective in most cases after reasonably quick exposure times.
