Custom compounding allows tailoring FFKM properties for specific challenges. Harder 85–90 durometer grades improve extrusion resistance at 30,000 psi. Softer 60–70 durometer compounds reduce friction in dynamic applications. Filled systems incorporate PTFE or proprietary fillers for wear resistance. Color coding (black, white, red, green) aids identification in complex assemblies. Rap... https://globalsealstech.com/ffkm-seals/
