EnDura Z95X
EnDura® Z95X is a peroxide-cured, explosive decompression resistant HNBR compound. EnDura® Z95X provides good chemical resistance to sour gas (H2S), crude oil, lubricating agents, and oil additives, with superior resistance to carbon dioxide, water, drilling mud and amine corrosion inhibitors.
The EnDura® range of elite materials has been specifically developed for Explosive Decompression (ED) resistance in downhole, surface and subsea oilfield equipment.
The high mechanical strength and abrasion resistance of EnDura® Z95X makes it particularly suitable for dynamic applications.
