In turbulent times…

… it is particularly important to keep up communication. Reliable information provides security. We have adapted and reorganized our modus operandi to the current situation, but are still there for you.

All our magazines as well as our newsletters will be released as planned. With one exception: For the time being, we are switching all magazines to online only versions. Current information is available as always at www.gupta-verlag.com and you can find us on Twitter and LinkedIn. In addition you can reach us also at info@gupta-verlag.de.

Especially now, when almost all trade fairs, conferences, workshops and professional training courses have been cancelled, our specialist media offer you the opportunity to inform yourself or reach a broad audience with innovations and news from your companies – regardless of time and place.

It is therefore vital that the industry maintains its support for the trade media, especially now, so that we can continue to offer our services to all of you. Without this support it will certainly not be possible to carry on business as usual.

With every change – as painful as it may be – there are also new opportunities that we should embrace with courage and confidence.

Perhaps you can use the time to decelerate, to develop new ideas from the lessons learned? Perhaps you now have time not only to skim over the exciting article, but to read it in peace and quiet? Maybe there will be an opportunity to write the long planned technical article?

A Chinese proverb says: “When the winds of change blow, some people build walls and others build windmills.”

So let us build windmills together!

We are here for you and wish you all the best in these turbulent times!

But above all... stay healthy!

Project STOP – An initiative of the chemical industry to free the seas of plastic waste

Plastic litter is the main problem in the current plastics crisis. It is estimated that there are now more than 150 million t of waste plastic in the world’s oceans and between 4 and 13 million t are added each year. During the last K show in 2019, the world’s leading trade fair for plastics and rubber, whose main theme was the circular economy, PU Magazine  had the opportunity to talk to some of the companies that deal with the problem of plastic waste in the oceans and offer solutions. Borealis AG, an Austrian global chemical group producing polyolefins, bulk chemicals and fertilizers, is one of the companies actively tackling this major problem. We spoke to Craig Halgreen, Director of Sustainability and Public Affairs, about Project STOP, an initiative to stop the dumping of plastic waste into the oceans.

Ways out of the plastics crisis

An alliance of civil societies and NGOs has jointly issued 15 demands, calling on the German government to take decisive action to solve the problem of plastic waste in the environment. Industry associations such as the Gesamtverband Kunststoffverarbeitende Industrie (GKV) and the IK Industrie­vereinigung Kunststoffverpackungen do not see the ­demands as a suitable contribution to the debate on plastics and ­resource efficiency. In their opinion, the demands run the risk of jeopardizing the initiated course towards sustainable resource and ­recycling management as they cause uncertainty and a lack of planning and legal certainty for the economy.

A roadmap toward the harmonization of global VOC specifications

The Molded Polyurethane Foam Industry Panel (the Industry Panel) is pursuing a science-based approach to create a “roadmap” industry standard for providing recommendations and defining best practices for measuring volatile organic compound (VOC) emissions from automotive interior flexible molded polyurethane seating foam. The proposed industry standard will address the interests and requirements of OEMs in the three major global automotive markets: North America, Europe, and Asia. The comprehensive standard will leverage existing consensus standards from ASTM International, SAE International, ISO, VDA along with existing automotive OEM test methods to draft four best practice documents: (1) Foam processing and handling, sample production, conditioning, packaging, storage, shipment, and specimen preparation, (2) Test methods to measure VOC emissions, e.g. chambers, air sampling and analytical methods, (3) Data analysis and expression of results, and (4) Description and flowchart of combined documents – Unification document to form a comprehensive VOC Roadmap. This paper will discuss the Industry Panel’s approach for proposing an industry standard. The document was drafted using a collaborative website approach in order to get input from all of the VOC Roadmap team members. A comprehensive review of automotive emissions standards for measuring VOCs from components and materials was conducted to evaluate current practices that are used by the automotive industry. Many aspects of the standards such as sample collection, handling and conditioning requirements were compared to identify similarities, conflicts, and potential areas that may require clarification or research. A collaborative survey with stakeholders was done to determine which methods are being used and to obtain feedback from potential users of the standard. The results from the survey were useful to help harmonize the methods that are covered in the proposed standard.

Renewable bio-derived polyols and microbial susceptibility in polyurethane foam

A growing trend towards the use of renewable bio-derived polyols in polyurethane foams is observed in consumer and commercial applications. In particular, bedding, furniture and automotive seating manufacturers seek to comply with the market demand for bio-derived polyols because of their superior environmental profile. However, there is concern about their potentially greater susceptibility to microbial contamination. Under certain conditions, uninhibited fungal and bacterial growth can affect the mechanical integrity of the foam while creating unhygienic conditions in the home and automotive environments. In this article, we present our recent research into the influence of different polyol types and processing conditions on the tendency for fungal growth in polyurethane foams, using a variety of standard and non-standard tests. Data are presented relating to the performance of antimicrobial additives, with the goal of defining optimal solutions for commercial applications.

End of life of mattresses and furniture in Europe

The European Union’s waste legislation has been deeply amended in 2018 in view of strongly increasing re-use, preparation for re-use and recycling of solid municipal waste between now and 2035. The new legislation will over time require a significant shift in the way end-of-life mattresses and furniture are dealt with. Landfilling will be nearly phased out and incineration will be strongly discouraged. As these are the main ways of treatment of end-of-life mattresses and furniture today, collection, dismantling and recycling of components mattresses and furniture are made of will have to increase drastically. Considering that mattresses and furniture are the two main markets for flexible polyurethane foam produced in the EU, the new EU waste legislation will require the development of new industrial-scale solutions for increased recycling of flexible polyurethane foam, as currently available mechanical recycling processes would not be able to absorb the volume of end-of-life flexible PU foam diverted from landfill or incineration. A number of research consortia have been created in Europe, often with support of public funding, to seek to develop such recycling technologies for flexible polyurethane (PU) foam. While research is ongoing, it is the view of the European flexible PU foam industry that – in order to succeed in diverting from landfill the significant volumes of end-of-life PU foam considered – a variety of technologies will be required in the future, including waste-to-energy for the fraction of material that cannot be recycled otherwise.

One of a kind in the polyurethane toolbox

A new bifunctional polymeric diisocyanate (BPI) has been recently launched on the market that is based on renewable carbon and is characterized by very low viscosity (150 mPa·s at 25 °C). Studies have shown that BPI is of interest not only in solvent free or low solid system but also as a building block for the polyurethane chemistry. The synthesis of thermoplastic urethane (TPU) and polyurethane dispersions (PUD) have been achieved, showing that BPI can improve the flexibility of the final material.
