Z85L is a peroxide-cured, HNBR compound specially developed for service in low temperature applications.

The high mechanical strength of Z85L provides excellent wear and abrasion resistant properties when used in dynamic applications.

Its broad chemical resistance makes Z85L ideal for use with sour gas (H2S), crude oil, carbon dioxide and operating fluids including lubricators, drilling mud, oil additives and amine corrosion inhibitors.

Key Attributes

Good explosive decompression resistance

Outstanding low temperature performance

Excellent chemical resistance

Superior H2S resistance compared with standard HNBR

High mechanical strength

Typical Applications

Low temperature and high pressure environments

Exploration and drilling equipment

Cementing and completion equipment

Subsea valves and pumps
