Z70F is a medium acrylonitrile (ACN = 34%), HNBR compound formulated using only those ingredients determined by the US Food and Drug Administration (FDA).

The high mechanical strength of Z70F provides excellent wear and abrasion resistant properties when used in dynamic applications.

Z70F offers excellent steam and chemical resistance to a broad range of media, making it ideal for use in various applications requiring FDA and 3A compliance. It is suitable for use in all food contact applications including dry, aqueous and fatty media.

Available in any sized O-ring (fully moulded up to 2.5m/8ft internal diameter) and custom designed profiles and components.

Key Attributes

Excellent chemical and steam resistance

Higher maximum operating temperature than standard nitrile (NBR)

High mechanical strength

FDA compliant - extraction tested to CFR 21 § 177.2600 (e,f)

3A Sanitary Standard 18-03 Class 3 compliant

Free from Animal Derived Ingredients

Typical Applications
Recommended for use in food and dairy production and processing equipment, for both static and dynamic applications.
