These shoes are made for ....recovering

The pandemic has taught us many things, and exploring the possibilities of digital encounters is one of them. A good example of an all-round successful virtual collaboration is Joe Nimble's recoverToes project. The shoe was realized within a few months, and the collaboration with Huntsman, the material supplier for the polyurethane materials used, was entirely virtual.

So the signs are good for recovery - not only for battered feet, but also for the battered economy. In this issue of PU Magazine, we are pleased to present several market reports (from Amaplast and Composites Germany, among others) that provide a positive overall outlook on economic developments.

And even though we are now able to work virtually in a virtuoso manner, everyone is surely longing for the time when we can meet in person again. For the autumn 2021, in any case, the signs are good and we are looking forward to European Coatings Show, Utech Europe, Europur meeting and many more ...

The pandemic has also taught us to pay more attention to our living environment. Matteo Grigolini from CSIL takes a look at the furniture industry in Latin America and we have news on mattress recycling. The VDMA reports about how circular economy and carbon footprint can act as drivers for lightweight technologies. Further improving sustainability and safety of continuous sandwich panel concepts are two major drivers for Pearl Polyurethane's brand new R&D initiative in Dubai. Precious insights into the markets for polyurethane chemicals and products in Asia Pacific 2021 are shared by IAL Consultants. Concentrol's Joaqim Serra gives an overview on release agents. We report about the cooperation of AniForm and Moldex3D for improved RTM analysis. And a new technology for less glass breakage and trimming in car glass PU encapsulation is presented by BBG.

Focus on mattress recycling – The Netherlands – a world leader in the collection and recycling of mattresses

According to Europur, the European Association of Flexible Polyurethane Foam Blocks Manufacturers, every year over 30 million mattresses are discarded in the European Union. Were they all stacked on top of each other, the pile would be 678 times as heigh as Mount Everest. In the Netherlands alone, 1.5 million mattresses are discarded on annual basis. That’s a potential waste pile of 100 times the height of the Eiffel Tower.

Fraunhofer IAP: Surface analysis at the highest level

Only a few atomic layers determine whether a surface is water-repellent, printable, paintable, adhesive or antibacterial. The surface of many products is therefore specifically modified. Thanks to a new X-ray photoelectron spectrometer, the Fraunhofer Institute for Applied Polymer Research IAP in Potsdam-Golm, Germany, can now analyse surfaces even more precisely, which is helpful when developing a process or determining sources of failures. Companies and partners can benefit not only from the new analytical capabilities at Fraunhofer IAP, but also from the extensive expertise in material development, which facilitates the interpretation of data and the tuning of a manufacturing process.

New PU flush sealing concept for encapsulating moulds – Less glass breakage and trimming in car glass PU encapsulation

Automotive glass that is encapsulated in moulds on the basis of BBG’s new PU flush sealing concept is much less prone to breakage than with conventional moulds. The reject rate decreases noticeably while encapsulation with polyurethane is more precise. As a result, necessary rework is reduced to up to a quarter of the time originally spent on reworking components. According to BBG, a manufacturer of moulds, machinery and plants, this is reported by customers who already rely on the new technology. It can be used for single-pane tempered glass, as well as laminated glass, and “fragile” semi-tempered glass.

Nine criteria for characterising micro- and macroplastics in soils

The issue of plastic waste has become part of all social debates. However, the pollution of the ecological system soil still receives little attention. So, the question arises whether plastics that remain on soils or fields (including water from drainage systems) do not have similar effects on the environment as, for example, in seas, rivers or lakes. Researchers of the iMulch project succeeded in establishing the first three test criteria for determining microplastics in the ecological system soil.

Successful production of paint protection films – Machinery and resin considerations

PPF is a thermoplastic urethane (TPU) based “self-healing” film applied to paint surfaces for added protection. Applications in the automotive, aerospace and electronic industries have already been highly successful. According to TPU industry reports, the global market for PPF is projected to reach 1.2 billion USD by 2026. This article summarises elements of a successful PPF production and how equipment suppliers such as Davis-Standard can help to engineer a solution on an existing line or new PPF line.

PPF was first developed and used by the US military during the Vietnam War to protect vulnerable parts on military transports. It proved very effective for protection of helicopter blades and other sensitive parts prone to damage by flying shrapnel and debris. Today, it is commonly used on automobiles to protect paint from stone chips, bug splatters and minor abrasions. The typical cost of PPF for full body coverage of a vehicle can range from USD 3,000 to USD 8,000. It is also used on airplanes, RVs, cell phones, electronics, screens, motorcycles and for many other purposes and even in specialty markets such as wind turbine blade protection.
