Sustainable aviation fuel (SAF) is changing what the industry demands from sealing materials, and our Greene Tweed experts, Andrew Clarke and Becky Petry, have the data to show how our Fusion® FKM compounds (731, 772, and 665) respond. In a recent Aero Mag article, they examine performance across key SAF pathways, including FT-SPK, HEFA-SPK, ATJ-SPK fuels, and SAK-enhanced blends.
Key takeaways include:
- Reliable hardness retention during dry-out, fluid ageing, and fuel-switching scenarios
- Controlled volume swell at temperatures up to 125°C
- Consistent performance across diverse SAF chemistries
