In Pennsylvania, Greene Tweed has released results from a study confirming the compatibility of its fluorine-based elastomer seals with SAF. The results provide critical insights for aerospace leaders transitioning to sustainable, low-emission fuels, while ensuring safety and reliability, the firm said. As the aerospace industry focuses on decarbonization, SAFs offer substantial CO2 reductions of over 65% compared to traditional jet fuels. Nevertheless, challenges like seal compatibility remain, said Greene Tweed. To address this, the company said it conducted rigorous testing to ensure its seals perform effectively with these advanced fuels. “Sustainable aviation fuels offer a practical path to reducing emissions, particularly for long-haul flights, where batteries and hydrogen remain less feasible,” said Shawn McCloskey, Greene Tweed Chief Commercial Officer. “Our study ensures aerospace customers have reliable seal solutions for SAF adoption without compromising safety or performance.” Greene Tweed collaborated with multiple suppliers to evaluate SAF blends and their effects on the physical properties of fluorine-based elastomers FKM and FVMQ. The study assessed performance in SAF blends, including Synthetic Paraffinic Kerosene (SPK) and Synthetic Aromatic Kerosene (SAK), following ASTM D7566 standards. Testing simulated extreme aerospace environments, including temperatures up to 120°C and prolonged SAF exposure.
