    Polypropylene recyclates: best quality at minimum cost thanks to precise stabilisation

    Press release / November 06, 2024

    Online_Rheologie_Teaser

    All organic substances, including plastics such as polypropylene (PP), undergo auto-oxidation in the presence of oxygen. This happens millions of times faster at the high temperatures of compounding and injection moulding. The result for PP is a degradation of the polymer chains, i.e. a reduction in molecular weight, which means that products made from these plastics can no longer be recycled. Antioxidants added during the manufacturing process slow down this degradation. Without these additives, many everyday objects could not be produced in a usable form. Researchers at the Fraunhofer Institute for Structural Durability and System Reliability LBF have further improved the rheological online tests so that the exact additives can be determined more quickly, and the costs optimised.

    Recyclable lightweight battery housing and a second life for old battery cells

    Press release / June 06, 2024

    Batterigehäuse aus Kunststoffrezyklat /Battery housing made from recycled plastic

    Lithium-ion batteries from electric vehicles lose their charging capacity during the use. Therefore, they are no longer suitable for vehicle operation from a ca-pacity loss of 20 percent, as the range and fast-charging capability are reduced. However, the remaining capacity of 80 percent is sufficient for a stationary storage application. In the CIRCULUS research project, several Lithium-ion trac-tion batteries already in use are being converted into a stationary storage sys-tem. The innovative lightweight design of the overall system ensures that the system can be dismantled according to type. This minimizes the sorting effort, resulting in high-quality material flows and thus implementing a functional and sustainable circular economy. Fraunhofer LBF will be presenting the results of the CIRCULUS research project at the Plastics Recycling Show Europe, Amster-dam, June 19-20, 2024, booth A22. Visitors will gain a comprehensive insight into Fraunhofer LBF's wide-ranging expertise in recyclates.

    additive Folienanlage Fertigungsprozess

    The use of recycled plastics is becoming increasingly popular due to its potential to reduce the environmental impact of plastic waste. However, the quality of recyclate materials significantly affects their application. With the exception of slightly damaged production waste, recycled plastics cannot be used in their original form. Usually, they are sorted, cleaned, and reprocessed to form usable granules. However, the recycled material's stability and processing ability for its intended application often require post-stabilization with suitable additives. Fraunhofer Institute of Structural Durabiity and System Reliability LBF has developed new formulations for enhance the quality of new recyclate films. At Plastics World Expo Europe, Essen, June 14-15, 2023, Booth C834, the researchers will give more information.

  • Online rheological investigations, Development, Plastics / 2023

    Fraunhofer LBF develops new approach for rapid process stabilization of plastics

    Press release / April 26, 2023

    Plastic materials are prone to degradation by atmospheric oxygen. These auto-oxidation reactions occur at ambient temperature already but become especially relevant during melt processing. Adding antioxidants to the polymers results in a pronounced slowing-down of the oxidation processes. Only by this way, the production of the well-known plastic parts by injection moulding, for example, is possible. Developing new plastic grades is accompanied by lengthy experimental procedures to optimize the antioxidant content. Researchers at Fraunhofer Institute for Structural Durability and System Reliability LBF see online rheological investigations as a promising method for accelerating the development process.

    Better recycling of plastic packaging: New process extracts fragrances

    Press release / April 20, 2023

    What doesn't smell good is hard to recycle. This simple rule also applies to the growing volume of plastic waste worldwide. One way to recycle it in an environmentally compatible and climate-friendly manner as high-quality post-consumer recyclates is through improved sorting and reprocessing. Until now, the reduced material quality has considerably limited the reuse of plastic recyclates, and this is mainly due to their odor. Scientists at the Fraunhofer Institute for Structural Durability and System Reliability LBF have developed a new environmentally friendly process on a laboratory scale to remove odors from plastic packaging. Fraunhofer LBF will present the results of the research project at the Plastics Recycling Show Europe PRSE, Amsterdam (May 10 to 11, 2023, Hall 11, Booth P3) and at Plastics World Expo Europe, Essen (June 14 to 15, 2023, Booth C834).
