The primary failure mode addressed by RGD resistant HPHT seals is explosive decompression. Gas molecules diffuse into the elastomer under prolonged high pressure. Upon rapid depressurization, trapped gas cannot escape quickly enough, creating internal voids and fissures. Materials with high modulus, low gas permeability, optimized crosslink density, and high tear strength mitigate thi... https://globalsealstech.com/product/rgd-rapid-gas-decompression-o-rings/
