Durlon® 7900/7925/7950 Aramid/NBR

Application:

An economy grade general service compressed sheet with NBR rubber binder for mild service in piping and equipment and OEM applications in steam, hydrocarbons and refrigerants. An economical alternative when service ranges and applications are not severe.

Composition:

DURLON® 7900, 7925 and 7950 contain high-strength aramid fibres bonded with high-grade nitrile (NBR) rubber.

Anti-stick properties:

Much effort has gone into improving the anti-stick release agents of all compressed DURLON® products. All DURLON® compressed gasket materials have passed the MIL-G-24696B Navy Adhesion Test (366°F/48 hrs).
