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.

TERIS reaches milestone: Fraunhofer consortium develops new standards for tire analysis

In the “TERIS” project, the Fraunhofer institutes ICT, IGD, and IWM—led by the Fraunhofer Institute for Structural Durability and System Reliability LBF—have reached a decisive milestone. For the first time, the teams aim to generate, analyse, and predict tire wear in the laboratory in a standardized and practical manner. As part of this milestone, results are now available on reference abrasion, particle analysis, tribological models, AI-based surface analysis, a test bench concept, and methods for accelerated aging and VOC detection. The tire industry, testing services, and environmental agencies will in future benefit from reliable, rapid laboratory procedures for emissions assessment.

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.

Aachen Summer School: Textiles become smart through 3D printing and origami

From 21 to 29 September 2026, the Aachen Summer School will transform Institut für Textiltechnik (ITA) of RWTH Aachen University into a laboratory of the future: over the course of a week, students will use origami folding techniques and 3D printing to develop active textile structures capable of performing programmable movements. This interdisciplinary event combines theoretical foundations with practical prototyping – from digital modelling right through to functional textile prototypes.

25 years of medical devices: ITVP combines experience with innovation

ITV Denkendorf Produktservice GmbH (ITVP) is celebrating its 25th anniversary. On October 1, 2001, ITVP was founded as a subsidiary of the German Institutes of Textile and Fiber Research Denkendorf (DITF), Europe’s largest textile research center. This spin-off company made it possible to consolidate expertise in medical technology and significantly expand production, which had previously been initiated mostly in the DITF’s cleanrooms.

An eco-friendly alternative to fluorocarbon treatments

Protective and outdoor clothing derives its durable water-, dirt- and oil- repellent properties from the application of fluorinated polymers or per- and polyfluorinated low-molecular- weight chemicals (PFCs). The beneficial properties thus achieved on textiles are offset by environmental and human health risks. For manufacturers of sports, medical, protective and automotive textiles, researchers at the Sächsisches Textilforschungsinstitut e.V. and the Leibniz Institute for Polymer Research have developed liquid-applied dispersions and solutions to functionalise textiles without the use of fluorine.
