Bio-based polyesters for challenging long-term applications

Current bio-based plastics are often only suitable for short-lived applications, such as packaging, because they have inadequate long-term properties. The new project “Bio-based polyesters for challenging long-term applications” from the Fraunhofer Institute for Structural Durability and System Reliability LBF aims to improve the long-term properties of bioplastics through targeted additivation in order to enable their use in technical applications. To do this, the researchers are looking for companies along the value chain that would also like to substitute petro-based plastics with bio-based solutions in long-lasting products.

In the planned project, bio-based materials will be optimized through targeted additivation to be comparable to petrochemical plastics. In numerous projects in recent years, researchers from the Fraunhofer Institute for Structural Durability and System Reliability LBF have conducted research in the field of plastic additives and can improve the long-term properties of plastics made from both fossil and renewable raw materials. The aim of the project is to replace petrochemical-based technical plastics in a sustainable way based on the knowledge gained so far in material optimization and to implement this along the entire value chain.

Minimal changes in the manufacturing process

The project addresses the challenges of the long-term properties of bioplastics. In a comprehensive literature review, existing data on long-term stability and the stabilizers used are first compiled. Together with the project partners, a specification sheet will be created that defines the material properties to be achieved. Market-available bioplastics and additives will be identified and tested for their properties. The modification of the bioplastics will be carried out by developing new formulations on a pilot plant scale. The aim is to enable material substitution with minimal changes to existing processing methods.

The Fraunhofer scientists are looking for partners from companies along the value chain, starting with manufacturers of plastics and additives, and including companies that want to substitute individual components in their designs, with a particular focus on developers and producers of finished components.

The use of novel additive systems should extend the life cycle of bio-based polyesters.

Securing competitive advantages together: sustainable, sophisticated plastic products

OEMs and manufacturers of plastic components in the construction, automotive, sports and leisure, electrical and electronics, and household appliance sectors who want to replace petrochemical-based plastics with bio-based solutions will gain sufficient knowledge to optimize their own research and development in a targeted and individualized way by participating in the new project “Bio-based polyesters for demanding long-term applications”. They will benefit directly from the latest findings, thereby securing competitive advantages. Raw material and additive manufacturers can expand their existing product portfolio with new applications, and compounders can prepare for future challenges in the use of bioplastics.

High-performance elastomers and plasma polymer coatings to replace fluoropolymers in technical applications: new Fraunhofer project

Users of poly- and perfluorinated alkyl compounds (PFAS), also known as "forever chemicals", are under pressure due to regulatory proposals from the European Chemicals Agency (ECHA). This also affects the use of fluoroelastomers, whose economic significance is enormous. Fraunhofer experts initiated the "HATE-Fluor" project at the beginning of February. Together, they want to develop high-performance elastomer compounds to replace fluoropolymers in certain technical applications.

More safety and comfort for protective clothing thanks to auxetic fabrics

When everyday materials are pulled, they stretch or elongate in the direction of the pull and become narrower in cross-section. We can also observe this property in two-dimensional textiles. Auxetic structures behave differently here. They have the striking property of not changing under tensile stress or even increasing their width or thickness. These properties are advantageous, for example, in protective textiles or textile filter media. The DITF are researching auxetic fabrics for various applications.

Fraunhofer CCPE presents the “Monomaterial Design Set” – Innovative solutions for circular product design

Composite materials made from different types of plastic often extend the lifetime of products but make recycling more difficult in the circular economy. That is why Fraunhofer CCPE has developed the “Monomaterial Design Set”. This new approach helps to reduce the variety of plastics used in durable products and offers circular solutions for designers and product developers.

How innovations drive BASF’s success

“Innovation has always been part of BASF’s DNA. Especially in these volatile times, it is crucial to leverage our innovative strength to develop competitive solutions that differentiate us as a company in our markets and give us a competitive edge,” said Dr. Stephan Kothrade, Member of the Board of Executive Directors of BASF and Chief Technology Officer, at the company’s Research Press Briefing held today. To achieve this, BASF implemented its “Winning Ways” strategy about a year ago with the clear goal of becoming the preferred chemical company to enable its customers’ green transformation.

Small tolerances, big impact and a recyclable alternative to elastane

ITA Master's student Janne Warnecke investigated tension differences over the fabric width in the weaving process and thereby contributed to quality assurance; ITA Bachelor's student Jasmin Roos found a basis for the development of recyclable yarns and textiles. For these developments, they were awarded the Walter Reiners Foundation's Promotion and Sustainability Prizes on 27 November. Peter D. Dornier, Chairman of the Walter Reiners Foundation, presented the awards at the Aachen-Dresden-Denkendorf International Textile Conference (ADD-ITC) in Aachen, Germany.

Texpertise Focus AI: Messe Frankfurt puts Artificial Intelligence centre stage at its international textile and apparel trade fairs

Under the banner 'Texpertise Focus AI, Messe Frankfurt will place a strong emphasis on Artificial Intelligence (AI) across its international textile and apparel trade fairs from 2026 onwards, setting a future-shaping signal for the industry. The initiative highlights the responsible use of AI along the entire textile value chain, from fibre production to the point of sale. The programme will launch at Heimtextil in Frankfurt in January 2026.

Autoneum and Polestar set new benchmarks for passenger experience and sustainability

As the global market leader in sustainable acoustic and thermal management, Autoneum is a key supplier of interior and exterior components for the highly anticipated Polestar 5 model. The successful collaboration between Autoneum and Polestar marks a significant milestone in sustainable automotive engineering: the electric grand tourer sports car features several innovations in lightweight, fully recyclable polyester-based components that ensure a superior driving experience. Polestar 5 was revealed at the IAA Mobility 2025 in Munich and is available in 24 markets.
