Material selection for RGD resistant HPHT seals prioritizes hydrogenated nitrile butadiene rubber (HNBR) and fluoroelastomers (FKM) with optimized formulations specifically engineered for explosive decompression resistance. HNBR provides excellent RGD resistance through its saturated polymer backbone reducing gas permeability while maintaining elastomeric properties to 350°F.
