Challenges and innovations
The book’s final 6-page chapter discusses future challenges and innovations for flame retardant polymers, as seen by Henri Vahabi, Lorraine University, France and Mohammed Reza Saeb, Gdansk Medical University, Poland. The complexities of formulation of FRs with polymers are underlined, in particular compatibility with the polymer(s) and with other additives, ensuring effective dispersion and stability in the polymer matrix. Sustainability is identified as an important driver for innovation, in particular the move to replace halogenated FRs. Opportunities for flame retardant innovation are identified in 3D-printing, which has specific needs for FR-polymer compounds; in the application of machine learning to accelerate design of new FR molecules and support formulation; and the need for FR solutions to help address the specific fire safety challenges of batteries and of next-generation computer equipment.
Challenges identified for FR development and polymer compound formation include:
- Scale-up from R&D to industrial production and regulatory authorization,
- Extrapolating understanding of FR fire performance from small-scale tests,
- Designing synergies between several FRs in formulations,
- Placing FRs at key sites within 3D-printed articles to achieve fire safety, minimise overall FR load, optimise polymer performance,
- Development and industrial implementation of bio-based FRs,
- Nano-scale FRs: balancing performance and dispersion benefits versus possible regulatory concerns,
- Using machine learning to predict fire performance of polymer – FR formulations,
- Sustainability: circularity, life cycle assessment.
