From the Sector

As of April 1, 2024, Eva Baumann takes over the position of CEO in CHT. Together with Prof. Dr. Klaus Müller, who acts as CFO, she forms the management of the internationally active CHT Group.

Until 2020, Eva Baumann had worked for many years in a leading global company in the chemical industry. She has been part of the CHT Group since January 2020 and, as Group Vice President, has headed the Business Field General Industries at Group level. As CEO, Eva Baumann is now responsible for Marketing, Sales, Corporate Strategy, Human Resources and Sustainability.

Eva Baumann has ambitious plans for the future of the CHT Group: "Together with my management team, I will continue to expand the CHT Group as a successful and profitable specialty chemicals group. We focus on what we have been particularly good at for over 70 years: turning innovative ideas into specialty applications. These ideas help our customers to secure their success and at the same time make a sustainable contribution to development. Our customer proximity and the outstanding quality of our products and services set us apart in the market.

Hexcel will continue to celebrate its 75th anniversary and highlight its latest developments for the Marine market at METSTRADE 2023 on November 15-17. Hexcel will showcase innovative advanced lightweight material technologies including new intermediate and high modulus fiber HexPly® M79 prepregs and present example high-performance superyacht and windship components developed by customers using Hexcel materials.

The new intermediate modulus prepreg combines the low temperature curing and simple processing of the DNV GL accredited HexPly M79 resin system with the market-leading stiffness of HexTow® IM2C fiber, creating a uniquely optimized composite material for highly loaded components. Originally developed to provide best-in-class performance for America’s Cup and IMOCA hull and deck structures, the new combination minimizes structural deformation under load in parts such as rigs, foils, and other appendages.

For a high modulus solution, HexTow® HM54 fiber is also now available with the HexPly M79 resin system. The unique mechanical properties of HexTow HM54 fiber allow structural designers to achieve higher safety margins for both stiffness and strength critical applications. Both products can be manufactured with Hexcel G-Vent technology for out-of-autoclave processing, delivering a reduction in process time and cost without compromising mechanical performance.

Hexcel will also display customer products that have benefited from the performance and processing gains provided by HexPly materials. A section of a Solid Sail mast made using Bureau Veritas (BV)-approved HexPly® M9.6 prepregs will be exhibited at METS. Such masts are used for wind propulsion and, by harnessing the power of ocean winds, they reduce reliance on engines, reducing fuel usage and emissions.

Visitors to the Hexcel booth will also see a section of a radar arch part from luxury motor yacht builder Sunseeker made using HexPly® XF surfacing technology and HexPly® SuperFIT semi-pregs. The part is lighter in weight and stiffer than versions made using resin-infusion processes and de-molds with a pinhole-free surface that needs minimal preparation to be ready for painting. Sunseeker has recorded an overall reduction in process time and material costs of around 30% against traditional prepreg parts, using Hexcel composite materials.

"Climate neutrality" and comprehensive social responsibility  
In the implementation of the sustainability strategy of the CHT Group, the field of action "climate neutrality" takes a central role. The CHT Group has set itself the goal of being climate neutral both in its own production and in the supply chain from the year 2045. The path to climate neutrality by 2045 is illustrated in the report as part of the strategic goal.

In addition to climate protection, social responsibility is also a top priority for the CHT Group. The continuous improvement of health protection and occupational safety is a top priority for the company.

From CHT's point of view, qualified and committed employees make a significant contribution to the company's future success. For this reason, the CHT Group promotes the professional and personal development of its workforce to a high degree and invests in future-oriented and targeted training and further education of its workforce.

For the CHT Group, the respect for human rights is an indispensable pillar of the corporate culture and an essential part of the group-wide Code of Conduct. In 2022, the Human Rights Compliance Policy Statement was developed, and compliance processes and measures were put in place to prevent any violations and identify and mitigate human rights related risks.

Die CHT Group, a worldwide company for chemical specialties, has built a new production facility in Meghna Industrial Economic Zone (MIEZ), Narayanganj which was inaugurated on May 9th, 2023.

Martin Stangs, Regional Sales Manager APAC Auxiliaries at CHT says: “The long-term success story with RH Corporation now comes to an even higher level. In addition to the decade-long service provided by motivated colleagues of RH Corporation and constant visits by well-experienced CHT application field colleagues, CHT products will now be made available locally by our new production facility at CHT Bangladesh. This will further enhance our current high-end offer with in-time deliveries which are now possible. The well-known services provided by our up-to-date laboratory facility in Dhaka will continue to prevail. This is all supported by the profound analytical and technical equipment at CHT Germany as well as CHT Switzerland. Less water, less energy, less time, but still “fit-for-purpose performance”: these requirements are no strangers to us. In alignment with our CHT Group policy ‘We take care’, we will solve these problems, too”.

Sustainability is anchored at CHT Group and plays an important role in Bangladesh, too. The new facility of the CHT Group in Bangladesh contributes to sustainability in more ways: The roofs of two buildings are fully covered with solar photovoltaic modules. For a proper use of natural light all the other buildings have periphery glass and transparent roofs There are additionally a ground water tank to harvest rainwater as well as a biological effluent treatment plant to reuse treated water as process water in the plant.

Fibres, fabrics, epoxy resins and adhesives from Sicomin have been used by Grand Largue Composites (GLC) to construct the first Class40 racing yacht to feature a significant quantity of flax-fibre reinforcements.
The yacht, called Crosscall, won the Class40 World Championships in June 2022 and is a prototype of the new Lift V2 design by Marc Lombard, one of the leading naval architects in this field.

Class40 is one of the most competitive fleets in yacht racing. The hulls of Class40 yachts must be light in weight, strong and stiff, and durable in the most extreme of conditions. Furthermore, to keep costs down, they cannot be reinforced with carbon fibres. The quality and reliability of the resins used for the infusion and lamination of the hulls are therefore of paramount importance.

Crosscall's cockpit was designed to be effectively non-structural, with the mainsheet, which can generate huge shock loads, supported separately. This would allow the cockpit to be made from a hybrid biaxial fabric comprising 50% flax fibres. Other parts of the boat that incorporate flax fibre include the tunnel, the engine cover, the ballast tanks and the cap. The rest of the boat is reinforced with 100% glass-fibre fabrics.

To help it realise this ambitious design, GLC, an infusion specialist, turned to its long-time material supplier, Sicomin. The hull was moulded and infused in one piece and the deck – including the hybrid flax-fibre cockpit – was also infused as a single part. The internal structure was then laminated into the hull by hand before the hull and deck were finally bonded together.

The infusion resin selected was Sicomin’s SR 1710, a high-modulus structural epoxy. Designed specifically for use in infusion and injection processes, it has exceptionally low viscosity and its low-reactivity hardener makes it suitable for the production of large parts. Composites components made from SR 1710 possess high interlaminar shear-strength and the resin retains its mechanical properties in wet environments.

Sicomin’s low-toxicity SR 8200 was used to laminate the internal structures onto the skin of the hull. Ideal for hand laminating, this system includes a choice of hardeners with a wide range of reactivities, which makes it equally suitable for making large or small parts. The hull and deck were joined together with Sicomin’s Isobond SR 7100, which demonstrates high fatigue strength and is very resistant to microcracking.

An epoxy bonding primer – called Undercoat EP 215 HB+ and supplied by Sicomin’s sister company, Map Yachting – was applied to the moulds first to make demoulding easier. It also serves as an undercoat in the polyurethane exterior paint system that is used instead of gelcoat to protect the epoxy hull from UV damage.

Since the launch of Crosscall, GLC has started building a second Lift V2 Class40 and a third one is now planned, both for which Sicomin will supply the materials.

Recreational boaters now have an easy way to be more sustainable following the introduction of a new biocide-free (B-Free) fouling control range from AkzoNobel’s Yacht Coatings business.

The first product to be launched from the new B-Free range is B-Free Explore. It features a specially-developed, unique silicone polymer technology which produces an exceptionally smooth and slick hull – helping to reduce drag.

Fouling is controlled by preventing microorganisms such as barnacles, slime and algae from forming strong bonds with the hull of the boat. Any that do adhere can be simply wiped away by hand or water jet.

“We’ve developed high-performance technology which allows boaters to maintain a clean, smooth hull,” explains Simon Parker, Director of AkzoNobel’s Marine and Protective Coatings business. “It’s based on proven technology and exemplifies the restless spirit of innovation which has been the cornerstone of our International brand for more than 140 years.”

Adds Jemma Lampkin, Global Commercial Director for AkzoNobel’s Yacht Coatings business: “Boaters are becoming more aware of the impact they can have on the environment, but they still require technologies that deliver high-performance fouling control. B-Free Explore provides a stand-out solution for both of these challenges.”

Specially crafted for the leisure boat market, B-Free Explore is the culmination of a five-year development program. It can be applied to new hulls or directly to existing antifouling, without the need for the removal of the previous antifouling coating. This makes it simple for boaters to upgrade from their traditional coatings to the new technology.

The new product is also better for the marine ecosystem. Being biocide-free, it provides a smooth surface for improved hull efficiencies, which can lead to a reduced carbon footprint.

Currently being introduced in Northern Europe, B-Free Explore will be rolled out across Germany, the Netherlands, Norway and Sweden in January 2023.

More than 350 million tons of plastic are produced worldwide every year, and vast amounts of plastic waste simply end up in the environment. The circular economy offers enormous potential for keeping plastics in the loop and thus conserving resources and the environment. Since 2018, six Fraunhofer institutes in the Fraunhofer CCPE cluster have been researching how to make the plastics value chain circular, and Prof. Manfred Renner has been the new head of the cluster since August 2022. Research results, implementation projects and strategies to accelerate the transformation to a circular plastics economy will be presented by Fraunhofer CCPE at the first international Fraunhofer CCPE Summit on February 8 and 9, 2023 in Munich.

In a circular plastics economy, resources can be saved, products can be intelligently designed for long service life, and end-of-life losses can be reduced. Systemic, technical and social innovations are needed to make the transition from a linear to a circular economy a success. This is what the Fraunhofer Cluster of Excellence Circular Plastics Economy CCPE is researching in the three divisions “Materials”, “Systems” and “Business”. The cooperation of the six Fraunhofer institutes IAP, ICT, IML, IVV, LBF and UMSICHT enables a multi-stakeholder approach in which the appropriate R&D competencies are bundled.

Fraunhofer CCPE would like to present and discuss successful projects and research approaches on an international scale at the Fraunhofer CCPE Summit on February 8 and 9, 2023 in Munich. The summit is to become an international forum for exchanging ideas for solutions and innovations for a circular plastics economy.

Cross-industry collaboration - local, regional and international
Since August 2022, Prof. Manfred Renner, Institute Director of Fraunhofer UMSICHT, is the new head of Fraunhofer CCPE. He succeeds Prof. Eckhard Weidner, who has retired. “Cross-industry cooperation - very local, but also regional and international - is the elementary prerequisite for a functioning circular plastics economy. At the summit, players from all points of the compass will meet and network in order to rethink the plastics value chain together," explains Prof. Manfred Renner, adding, “We want to provide answers to the following questions:  How can we make all Circular Economy principles, i.e. the ten R-strategies, known? How can industry, science and society best cooperate in a transformation to a circular plastics economy for the greatest possible impact?”

Results of the Fraunhofer CCPE cluster so far are innovative approaches for circular business models, intelligent collection, sorting, and recycling technologies, but also new formulations for circular polymers and compounds to enable multiple recycling cycles. With the newly developed assessment tool CRL® , companies can, for example, self-assess the maturity of products or product systems with regard to the circular economy. The tool checks the extent to which a product already takes into account circular economy principles in the areas of product design, product service system, end-of-life management and circular economy, and where there is still potential for improvement.

Prof. Manfred Renner and Prof. Christian Doetsch will take joint leadership of the Fraunhofer Institute for Environmental, Safety and Energy Technology UMSICHT from August 2022. As renowned scientists, they have most recently shaped the direction of the institute as heads of the Products division and Energy division respectively, and will now follow in the footsteps of Prof. Eckhard Weidner, who has entered retirement.

This is the first time in its history that Fraunhofer UMSICHT is led by two directors. Both institute directors began their professional careers at the institute and from August they will have a joint hand in its future.

Prof. Manfred Renner holds a doctorate in mechanical engineering, specializing in process engineering and business development. Since 2006, he has held various roles at Fraunhofer UMSICHT, most recently heading up the Products division and overseeing its 126 employees and its budget of 14.8 million euros. He has set international standards through his award-winning research into a free of water tanning leather tanning process that uses compressed carbon dioxide. With the development of innovative aerogel-based insulation materials for building facades, he has made a significant contribution to environmentally friendly, circular applications in the construction industry and initiated a number of industrial projects. One of the notable technological breakthroughs made by his team was the development of a new type of fire-resistant glass, which can withstand even the most extreme heat. This won his development team the Joseph von Fraunhofer Prize in October 2020.

Alongside becoming institute director, Prof. Renner will also take over the leadership of the Fraunhofer Cluster of Excellence Circular Plastics Economy CCPE in August 2022. In this role, he will represent the Fraunhofer-Gesellschaft on a national and international level with regard to the transformation of industry and society to a circular economy. In addition, he will start his professorship in Responsible Process Engineering at the Faculty of Mechanical Engineering of the Ruhr-Universität Bochum. Over the course of his professorship, he will shape the systemic development of the circular economy at a corporate, regional and European level.

Prof. Christian Doetsch has worked in energy research for more than 25 years, spending most of this time at Fraunhofer UMSICHT. As head of the Energy division, he managed a team of around 145 employees and was responsible for a budget of approximately 10.4 million euros. His technological focal points are energy storage, Power-to-X technologies including hydrogen electrolysis and chemical conversion, catalysts, and energy system modeling and optimization. His overarching aim is the integration of renewable energies into a cross-sectoral, resilient energy system.

In 2015, Doetsch co-founded the award-winning start-up Volterion GmbH & Co. KG, which develops redox flow batteries. He attained high visibility on a global scale by redesigning stacks, one of the main components of redox flow batteries, an achievement for which he, his team and Volterion representatives were awarded the Joseph von Fraunhofer Prize in May 2021. The energy expert also acts as deputy spokesperson for the Fraunhofer Energy Alliance and task manager for the energy storage group at the International Energy Agency (IEA). He also co-founded the “Open District Hub e. V.,” an association that promotes the energy transition in the sector by means of energy systems integration.

Since January 2020, he has been Professor of Cross Energy Systems at the Faculty of Mechanical Engineering of the Ruhr-Universität Bochum. In this role, he conducts research into ecological evaluation and resilience of cross-sectoral energy systems.
