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.

Walter Reiners Foundation Prize awarded to three ITA graduates

Sabina Dann, Lukas Balon and Annegret Storm from the Institut für Textiltechnik (ITA) of RWTH Aachen University were awarded the Walter Reiners Foundation Prize by the German Engineering Federation (VDMA) for their master’s and bachelor’s theses. Peter Dornier, Chairman of the Walter Reiners Foundation, presented the awards during Techtextil at the VDMA stand in Frankfurt am Main, Germany.

Young talents honoured – 60 years Walter Reiners Foundation

At the Techtextil trade fair in Frankfurt at the end of April, Peter D. Dornier, chairman of the VDMA’s Walter Reiners Foundation, presented awards to five successful young engineers. Promotion and sustainability awards were presented in the categories of bachelor’s/project theses and diploma/master’s theses. Academic theses are eligible for the sustainability awards if, for example, they develop solutions for resource-efficient products and technologies.

Regional hemp bast for lightweight construction profiles

The cultivation of fibre hemp for the production of ropes and clothing has a long tradition in Saxony. Due to its excellent fibre properties, it is also suitable as a renewable raw material for reinforcement in fibre composites. At the STFI and IWU in Chemnitz, the CannaPul project is cur- rently investigating how a regional value chain for hemp-based lightweight construction profiles can be established. To this end, the technical processing of hemp fibres into continuous fibre strands and their embedding in a suitable bio-based matrix are being investigated.

Barmag and Neumag showcase innovations across all manmade fiber processes

For the first time, Barmag is presenting itself alongside its new parent company, Rieter: At this year’s ITM in Istanbul, both companies will be represented from June 9 to 13 at the Tüyap Fair Convention and Congress Center in Hall 7, Booth 702B. As a technology leader in the field of chemical fiber equipment, Barmag will showcase its entire portfolio of systems for filament yarn, staple fiber, and nonwoven production, as well as solutions for the networked factory.
