We really live in a very special time. We are experiencing how vulnerable so many things are that we previously thought were safe. We realize how fragile our lives are. Actually, this was already the case before Corona – we just always had enough distraction to keep us from looking. The value and importance of what we used to take for granted becomes clear: going to the office, visiting fairs and conferences, meeting friends, doing sports, hugging loved ones, ...
It is a time when many contradictory feelings arise in us. There is the fear for one’s own health and that of loved ones, the worries about financial and professional existence, the uncertainty whether we are on the right way and how to continue. But there is also the trust in us, the love for life, the joy about the “little” things and the confidence that everything has a meaning and that everything will be fine.
Everyone decides where to direct their attention and energy: to fear, in connection with greed, envy, egoism and resentment, or to confidence, tied to a sense of responsibility, trust, solidarity and love.
It is a crazy time - or maybe it is also a time for straightening things and standing up for what is really important to us.
It is a time in which everyone has to decide for themselves which way they want to go...
For my part, I feel a great gratitude for everything that has been given to me so far. Gratefulness for all the encounters in my life. Gratefulness for the opportunities that I have been allowed to seize again and again. Also gratefulness for being able to experience this time.
The team of the Dr. Gupta Verlags GmbH continues to be there for you. During this time, we are working to ensure that proven traditions are preserved and that new ideas are developed and allowed to grow.
Please remain loyal to us.
But most of all ... Stay healthy and positive!
The Center of Automotive Management (CAM) at University of Applied Sciences of Economy (Fachhochschule der Wirtschaft – FHDW) in Bergisch Gladbach, Germany, has been analysing the performance of global automotive manufacturers since 2004. Based on annual reports as well as market and innovation indicators, the financial and market-based performance levels of the automotive manufacturers are analysed and released in the regularly published AutomotivePerformance Reports. The following report presents some key statements of CAM’s current industry study “AutomotivePerformance Report 2020”.
IAL Consultants has released brand new information on polyether graft co-polymer polyols (GCPP) in the very first edition of its market study “Overview of the Polyether Graft Co-Polymer Polyol Market in Europe, Middle East & Africa”. This comprehensive review builds upon previous work in the polyol market, but with a focus on these high-value components. In addition, the market analysts announced the recent publication of the 2020 edition of their report on the markets for polyurethane chemicals and products in the Americas. The study “PU Chemicals and Products in the Americas 2020” updates and expands upon the information included in the previous report published in 2018. The information contained within this study is based upon an extensive programme of interviews throughout the industry. The report contains both PU production and raw material consumption figures, with 2019 as the base year and market forecasts provided to 2024.
Dr. Rüdiger Baunemann, managing director of PlasticsEurope Deutschland e. V. and Regional Director Central Europe and member of the Leadership Team of PlasticsEurope in Brussels, Belgium, died suddenly and unexpectedly in his home town Leun, Germany, on 17 April 2020 at the age of 58. With his death, the plastics industry loses a leading figure with great creative power, an innovator and pioneer who was committed to ensuring that the plastics industry was given the appropriate importance at both national and European level.
WindEurope, the European Chemical Industry Council (Cefic) and the European Composites Industry Association (EuCIA) have presented their recommendations for the recycling of wind turbine blades in their new report “Accelerating Wind Turbine Blade Circularity”.
Nowadays the use of plastics is mainly perceived as a problem. And indeed, their extensive use is a double-edged sword. On the one hand, we cannot and do not want to do without plastics, because the diversity of polymers and their broad spectrum of properties enable applications where traditional materials fail. In addition to their undeniable benefits in everyday life, they are also the cause and the content of a wide range of environmental problems. This article looks at what speaks for and what against the extensive use of plastics. Part 1 deals with the advantages of plastics for our high-tech civilization and highlights the general possibilities, limits and economic and ecological costs of recycling. In part 2, different groups of plastics will be considered individually and examined for their recyclability. Raw material recycling and incineration are also addressed as possible end-of-life solutions.
The polyurethane industry has already made major strides to meet the regulatory requirements to transition to low global warming potential (GWP) physical blowing agents. For use in rigid foams, common SNAP approved low GWP blowing agents commonly used in North America include pentanes and HFOs (1233zd(E) and HFO 1336mzz(Z)). Another viable option now available in North American market is methylal. Methylal has already been SNAP approved for most polyurethane applications. Compared to most other blowing agents, methylal offers superior solubility in most polyols and is generally highly compatible and stable with catalysts, surfactants, and flame retardants found in polyurethane systems. It also offers high blowing capacity, which is effectively twice that of available HFOs. Previous studies have demonstrated the benefits of using methylal in place or in combination with n-pentane and cyclopentane. In this paper, we are evaluating the performance of methylal in a model rigid polyurethane foam system as a drop-in replacement for a commercially available 1233zd(E) HFO. The impact of methylal on reactivity and functional performance parameter is evaluated, including blowing capacity, dimensional stability, compressive strength, and thermal conductivity. The results of this study can guide implementation of methylal in rigid polyurethane foam formulations.
Cellular polymer foams are being increasingly used in applications which demand both good insulating and mechanical properties. The compressive modulus (E) and strength (Cs) along with the glass transition temperature (Tg) are important properties in the development of rigid polyurethane (PU) foams used in various applications, particularly in insulation applications. In this work, we outline a methodology based on established concepts in polymer science to predict the uniaxial compression modulus, strength and the glass transition temperature for rigid polyurethane foams as a function of the formulation design variables. Results of the analysis are validated with experimental results. This could greatly accelerate the development of new rigid polyurethane foam formulations. This type of methodology could also be used for formulation optimizations for product performance and cost.
Flexible PU foams were developed and used in car seats in the early 1950s. In the 1990s, the first low-emission foams were developed and, due to emanations control, were extended to subsurface materials used, such as seat cushions. Raw material suppliers were asked to explore the sources of the emanations and work with OEMs to reduce their overall quantity. At that time, silicone surfactants played a key role in low emissions. A general overview on the emissions and the analytical methods used to analyze PU foam emissions was published in 2018 , but it focused mainly on emissions under well-established methods such as VDA 278 , which is one of the standard European methods. As other markets such as the Asia-Pacific economic zone may have different requirements and quality standards when emissions are considered, we summarize in this paper the main volatile components currently monitored in this region and how they are analyzed. We also discuss analytical data regarding the contribution of silicone surfactants to emissions and how they can be improved to meet customer requirements.
