RE3 – What’s that?

I admit that in retrospect, 2019 will certainly not be one of my favorite years in many respects, but uncertain and challenging times always bring something good with them, if you continue to move forward with confidence and courage, act counter-cyclically!

And so, in a time of economic uncertainty and the associated cutbacks in advertising budgets, trade conflicts, “plastic bashing”, and the demise of publishing houses, we have dared to launch a new magazine at K 2019:

The focus of RE3 is on Circular Economy. The three keywords “REduce”, “REuse”, “REcycle” appear again and again. In RE3 you can read what they stand for, and which interesting approaches and solutions are available. The magazine is published four times a year in German and English in PRINT and online. Visit and follow us also on Twitter and LinkedIn. Issue 01 will be published at the end of March.

The content of the magazine’s coverage focuses on solutions the industry is developing – new products, technical developments and information about companies that provide systemic solutions. In addition, it includes definitions of terms, scientific research results, pro-con comparisons, business news and articles about people in the industry and associations.

A critical view of the ongoing discussion is also necessary within the industry. Our focus is on a future-oriented and responsible handling of the valuable material plastics. “Green Washing” is out of place in RE3.

Although RE3 is not a technical magazine, it is managed in terms of content and sales by the expert staff of Dr. Gupta Verlags GmbH, who are also your contacts for all questions. RE3 is published by INDIGU Publishing.

With a new publisher, we have the opportunity to contribute with expertise and knowledge to the social discussion about the pros and cons of the various plastics in our everyday lives – extending the scope beyond the plastics industry.

Confident that our courage has paid off, and hopefully with your support, we look forward to communicating the know-how of the industry and the future possibilities and solutions to an ever broader audience.

Warmest regards
Indira Gupta

Global automotive markets 2020 – Industry under economic and transformation pressure

The automotive industry is under economic and transformation pressure worldwide. On the one hand, the transition to electric mobility must be shouldered. On the other hand, the poor state of the industry as a result of the US customs wars under President Donald Trump is causing concern. Switching to electro mobility will result in the loss of jobs in the industry, which cannot be compensated for by the growth processes in the coming years. Important value creation in the internal combustion engine sector will be lost bit by bit and replaced by highly automated battery and electric motor production.

The global bio-based polymer market 2019 – A revised view on a turbulent and growing market

Turbulent times for bio-based polymers in 2019: PLA sold out despite expansion, as did PHA. Bio-based PP available for the first time, increased production of PBAT, PBS, bio-based PE, starch-containing polymer compounds and epoxy resins. Lower production is seen particularly in bio-based PET. At the same time, there is a lack of support from policy makers, who are taking bio-based and biodegradable plastics into collective punishment with fossil plastics in the Plastic Policy. These are some of the findings of the new market and trend report “Bio-based Building Blocks and Polymers – Global Capacities, Production and Trends 2019 – 2024” from the German nova-­Institute. The report shows capacities and production data for all bio-based polymers in the year 2019 and a forecast for 2024. The market and trend report is written by the international biopolymer expert group headed by nova-Institute. The corresponding authors come from Asia, Europe and North America.

Chinaplas: Postponement 2020 and change of date and venue for 2021

One of the most prominent event victims of the Coronavirus was Chinaplas 2020. The major global event for the plastics and rubber industry was supposed to open its doors from 21 – 25 April 2020. Due to the outbreak of the Coronavrius the event is re-scheduled to 3 – 6 August 2020. The venue, the NECC in Hongqiao, Shanghai, ­remains the same. 


TPEs on the road to electric vehicles and autonomous vehicles

Automotive accounts for about 45 % of global TPE consumption. Within the automotive sector, ownership patterns are shifting toward electric vehicles (EVs), autonomous vehicles (AVs), semi-autonomous vehicles (semi-AVs), and various forms of ride sharing have entered the market. These shifts have created new functional roles for automotive TPEs. The new opportunities will result from broader performance requirements, the need to bring smart functionality (smart TPEs), more versatile fabrication process technology and shortened/shifting supply chains.

Effect of oxidic filler particles on dielectric properties of thermoplastic elastomers based on SEBS

This paper describes the effect of the oxidic filler particles barium titanate, titanium dioxide and zinc oxide on the dielectric properties of a commercial thermoplastic elastomer based on poly(styrene-block-ethylene/butylene-block-styrene) (SEBS) containing a high amount of plasticizer. The relative permittivities were determined in the frequency range between 20 Hz and 1 kHz by use of an alternating current testing bridge (LCR meter). A new method was developed to measure the relative permittivities at low frequencies in the range of 0.1 to 2 Hz. This method is based on the measurement of the normal force under action of an electrical field in an electro-rheological measuring cell. The increase of permittivities of SEBS composites due to the action of BaTiO3 and TiO2 are smaller than expected whereas ZnO caused a remarkable increase of permittivity that excels the predictions made by simple mixing rules.
At low frequencies, all composites and the unfilled SEBS exhibit a strong increase of permittivity that is caused by polarization at the interface. The relaxation of interfacial polarization at increasing frequencies can be described by Debye’s relaxation model for BaTiO3 and TiO2 composites and also for the unfilled SEBS matrix. On the contrary, the ZnO containing composites reveal also at higher
frequencies a frequency dependent behavior, which cannot be described by the simple Debye model. It is assumed that the very high specific surface area of the ZnO particles and the resulting high interfacial area between filler and polymer in comparison to the other composites cause the peculiar behavior of the ZnO composites.

Efficient testing and development of a visco-elasto-plastic material model for thermoplastic elastomers

Thermoplastic elastomers (TPE) show a strong non-linear material behaviour in combination with a stress softening after initial loading and a high residual deformation after unloading. This material property depends on the stress state as well as on the temperature. In order to consider this characteristic during the design and development of TPE parts, suitable material models have to be developed. An isotropic and incompressible TPE was used to develop a visco-elasto-plastic material model based on generally known material models. The calibrated model was validated on a sealing ring in order to show the deficits of the generally known materials. Furthermore, the dependence of the material parameters on the stress state and temperature was investigated to develop an efficient test plan for the calibration of the material model.
