PU Magazine International

Ausgabe 06 | 2021


Dear Reader

please allow me to introduce myself:

My name is Jörg Spangemacher. I have been a successful journalist and publisher for more than 40 years. During this time, I have turned each specialist title (German, English and Chinese) I managed into market leaders in terms of subscriptions and advertising sales.

After my family took over all shares in the company, I became the publisher and managing director of Dr. Gupta Verlags GmbH on 1 September 2021.

After a transitional phase, the publishing house will now be completely reorganized – to the bene t of all. Together with the most important editors, we are currently developing a new contemporary appearance with additional journalistic content. How this work is coming to life will be re ected in the  rst issue of each magazine next year.

At the same time, new, quali ed employees in administration and sales are modernizing the internal processes of our publishing house. All business areas are being reorganized, supported by the installation of state-of-the-art digital infrastructure for internal and external communication.

In this way, I can assure you that Dr. Gupta Verlags GmbH, with its high-quality German and international titles, will be led into a successful future - building on its traditional past.

Dr. Gupta Verlag is  rmly committed to the interests, goals and values of the rubber industry. Therefore, I will be pleased if your company recognizes this and your marketing budget will take our titles into account.

I would also like to invite you to send interesting and groundbreaking technical articles and presentations by your employees to our editors for publication at any time – but without advertising content. After all, a serious trade journal thrives on well-founded information, objective facts and open discourse from the industry whose interests it represents. This will only be possible if your company underlines its af liation with the industry with a statement in the form of trade-speci c advertisements – with the effect that you can address your customers directly.

If you have any questions or suggestions, please call me at any time or send me an e-mail:
Phone: +49 172 668 5550

With kind regards

Thinking aloud: Let us not recycle our recycling strategy

A lot is now happening to move the polyurethanes industry towards a circular economy. All the initiatives are to be applauded with hopefully many more to come. They argue that the “Time is Right” (at last?). Look at the policy makers…if the demand exists, supply will follow.


Polyurethanes in Automobiles – Horizon 2030 – An ICIS Study for Euro-Moulders, the European Association of Manufacturers of Moulded Polyurethane Parts for the Automotive Industry

At the annual conference of Europur and Euro-Moulders in Amsterdam in November, Euro-Moulders released a study commissioned from ICIS on “Polyurethanes in Automobiles – Horizon 2030”. This study is based on desk research and interviews of raw materials producers, polyurethane parts producers, Tier 1s and OEMs. It covers all types of polyurethane, not just exible foam and addresses key issues such as PU substitution, sustainability, recycling, e-mobility and end-of-life vehicles.


Market challenges by digitalisation, circular economy and sustainability – From the Europur and Euro-Moulders General Assembly 2021

After the 2020 event had to be rescheduled several times due to the Covid 19 pandemic, the Europur and Euro-Moulders annual conference nally took place in Amsterdam on 3 and 4 November 2021. Over 300 participants, a good part of the exible PU foam supply chain, including representatives of about 90 different companies, attended the event to discuss innovation and the future of the PU industry with a special focus on circularity.

No Business as Usual – Why the flexible PU foam industry must prepare for the future

Most people never heard of Rear Admiral Grace Hopper. Yet, this very article would not be published today if it was not for her work. Indeed, back in the 1950s, she was the rst to devise machine-independent programme languages such as Cobol, which is still in use today. She also famously said “the most dangerous phrase in the language is: we’ve always done it this way”.

Essential aspects in 2K injection molding with TPU as soft component

Multi-component injection molding technologies are gaining continuously increasing interest and market importance. They combine different materials and functionalities in one product and offer different part and design options, a high degree of automation, and high output rates in constant quality [1, 2]. Thus making it an economical solution over other established joining technologies such as welding or adhesive bonding. Multi-component products include versatile material combinations such as plastic-metal, plastic-glass, and plasticplastic. Hard/soft combinations based on hard thermoplastics and one or more soft thermoplastic elastomers (TPE) are omnipresent in daily products and play today a key role for nearly all industries. This article aims to give a comprehensive overview of the adhesion performance of thermoplastic urethane elastomers (TPU) in various TPU-based hard/soft combinations using different engineering plastics as hard components. The inuence of TPU hardness and TPU type as well as the inuence of the 2K injection molding process on the adhesion are shown and discussed. Furthermore, the inuence of the compound composition or additivation on the adhesion of the TPU is also addressed.
