CO2-based polyols are now entering service for the first time. Thanks to the development of a new process that can produce aniline – an important precursor for rigid MDI foam material – from renewable raw materials, the supply of PU raw materials could be improved in the future. Note de contenu : - Biomass-based aniline as precursor for MDI - Flexible foam : first applications for CO2-based polyols - Rigid PU foam : thermal insulation in metal sandwich panels - Rigid PU foam for cold insulation - TPU in flat and rigid variants - Pultrusion headed for a step-up in performance - Industry 4.0 and digital service - Tank farm assessment for users - FIGURES : 1. Production of bio-aniline is already occuring on a small scale. Now, the new proces is to be transferred to larger industrial dimensions in a pilot plant - 2. World premiere : for the first time a truck is loaded with carbon-dioxide-based polyol at the loading station of the new production plant - 3. The "House of Nation" in Bergisch Gladbach, Germany, consists of wall panels with rigid PU foam core. The panels, insulate well and are claimed to make the house affordable at 1150 EUR/m2 - 4. Desmocomp, a one-component, aliphatic PU, is used to make pultruded side components for a system unit in which the load can be stored on pickups and flatbed vehicles. This application requires teh materials to be UV-resistant and weathering-resistant En ligne : https://drive.google.com/file/d/1kYNv7uhlzsPxoEKsAoclau-I5_4HGazm/view?usp=drive [...] Format de la ressource électronique : Pdf Permalink : https://e-campus.itech.fr/pmb/opac_css/index.php?lvl=notice_display&id=29279 [article]

Polyurethane (PU) / Reinhard Albers in KUNSTSTOFFE INTERNATIONAL, Vol. 109, N° 10 (10/2019)  

[article]  inKUNSTSTOFFE INTERNATIONAL > Vol. 109, N° 10 (10/2019) . - p. 30-36 Titre : Polyurethane (PU) : The global PU sales reached a new record in 2018 with just over 20 million tons Type de document : texte imprimé Auteurs : Reinhard Albers, Auteur ; Lutz Brassat, Auteur ; Andreas Chrisochoou, Auteur ; Hubert Ehbing, Auteur ; Georg Fuchte, Auteur ; Andreas Hoffmann, Auteur ; Catherine Lövenich, Auteur Année de publication : 2019 Article en page(s) : p. 30-36 Langues : Anglais (eng) Catégories : Economie politique Études de marché Matières plastiques -- Applications industrielles Matières plastiques -- Industrie et commerce Polyuréthanes Index. décimale : 668.4 Plastiques, vinyles Résumé : In the midterm, a worldwide increase in PU consumption of 4 to 5 % per year is to be expected. Growth drivers are the sound economic performance in the major industrialized nations so far, and in particular the increasing prosperity in China and emerging markets. In future, the PU business will be strongly influenced by digitalization and the development of closed material life cycles. Note de contenu : - Global capacity expansion - TPU with good growth in Asia - Sustainable raw materials and stricter emission specifications for soft polyurethane foams - Efficient thermal insulation with rigid PU foam - PU in the cold chain- Focus on higher productivity - Better acoustics and lightweight construction - TPU for the "shoe well" - Recycling and shoe concept - Fig. 1 : Covestro wants to double its MDI capacity at Brunsbüttel, germany, with the conversion of the former TDI plans on MDI. The picture shows the 26 m high and 80 t air scrubber before being installed in the new MDI plant - Fig. 2: Reserachers of the Catalytic Center of the RWTH Aachen University, Germany. As part of the Carbon4PUR consortium, they want to develop a process that can convert waste gases from steel mills into polyols - Fig. 3 : Facade systems can be insulated very economically, efficiently and thinly with PU thermal insulation systems. The facades can even equal the insulation performance of a passive house facade - Fig. 4 : Examination of the dimensional stability of a metal composite element at the end of the production line in the Covestro PU pilot plant in Leverkusen, Germany En ligne : https://drive.google.com/file/d/1em9vbFQdwLktl71kg7zH49DvYD5LmC75/view?usp=drive [...] Format de la ressource électronique : Pdf Permalink : https://e-campus.itech.fr/pmb/opac_css/index.php?lvl=notice_display&id=33787 [article]

To do so, manufacturers are ‧taking measures such as using bio-based raw materials, chemical recycling, and CO2 as a synthesis component. Digitalization, electromobility, autonomous driving and the construction industry are also driving PU development. Note de contenu : - Digital business models - Chemical recycling projects - Using CO2 as raw material - Exchange of epoxy resin for PU in wind energy systems - Demolding cooling devices up to 20% faster - Figure : Insulation boards and metal composite elements are the primary applications for PU in the construction. Since buildings are responsible for 40% of global energy consumption, more efficient materials in this area can generate big savings, such as through improved - Fig. 1 : With the opening of thenew MDI plant, the Brunsbüttel is one of Europe's three largest production sites worldwide for thie PU preliminary product - Fig. 2 : Mattresses create a large amount of soft foam waste at the end of their service life. Because of this, many PU manufacturers are working for options for chemically recycling mattresses so they can be used again to manufacture PUF - Fig. 3 : Covestro has developed a material and production solution for efficiently producing wind energy rotor blades alongside industrial partners. This allows for longer, lighter weight rotor blades.
