New project at the Fraunhofer Institute: Looking for PFAS-free flame retardant solutions!

A new joint project called “CompoPFAS” has begun at the Fraunhofer Institute for Structural Durability and System Reliability LBF. The aim of this project is the substitution of PFAS (per- and polyfluoroalkyl substances) in flame-retardant formulations. This initiative follows a previous project that involved evaluating alternatives to PFAS and was supported by the participation of 21 medical technology and engineering companies. The research will focus in particular on understanding how fluoropolymers work and their possible substitutes, while supporting participants in the development of PFAS-free flame retardant compounds, as oekonews reports.

The project aims to carry out systematic research and investigations to develop new and efficient flame retardant formulations. The effect of additives such as fluoropolymers and low molecular weight fluorine compounds is also being investigated, as these are difficult to replace. In addition, the understanding of how fluorine-containing additives work should be improved in order to create the basis for new flame-retardant compounds.

Research approaches and methodology

The research includes recording relevant types of plastics as well as the focus of the participants in order to develop targeted research approaches. Compounding and injection molding campaigns to analyze fire behavior and other properties are also planned. The insights gained are iteratively integrated into the development process in order to create concrete recommendations for action on the selection and effect of possible substitutes.

In the current discussion about PFAS, the urgency of the issue is clear, as more than 10,000 PFAS are on the European Chemicals Agency (ECHA)'s proposed ban list. This list, published in February 2023, is currently being evaluated. ECHA proposes a ban on the production, use and supply of PFAS. The need to test and evaluate replacement materials is therefore more urgent than ever, as Fraunhofer explains.

Health and environmental implications

PFAS are not only important in industry, but also pose a major environmental and health risk. They are bioaccumulative and can have serious impacts on nature and people. They are often only used when the special properties of PFAS are essential, which makes easy substitution difficult. Participating companies are therefore required to better assess their individual situation and the challenges of a possible PFAS ban. The “CompoPFAS” project aims to address these aspects and find solutions that both meet safety requirements and are environmentally friendly.

In addition, the Fraunhofer Chemistry Alliance is advancing research and development topics in the context of PFAS substitution. These include, among other things, the development of methods for analyzing and evaluating PFAS as well as concepts for separating PFAS from water, as explained on the website of Fraunhofer Chemie.

Overall, it is clear that a rethink is necessary in the industry. The search for PFAS-free alternative materials has increased in many areas, and the “CompoPFAS” project is seen as a beacon of hope on this path. Companies should prepare for the new challenges and actively participate in the development of sustainable solutions.
