Application:
A good quality commercial grade compressed non-asbestos sheet for moderate service conditions where an ABS certified gasket material is required. DURLON® 5300 is suitable for steam, oil, water, mild alkalis, mild acids, hydrocarbons and solvents.
Composition:
DURLON® 5300 contains mineral fibres bonded with nitrile (NBR) synthetic rubber. A release agent on both sides provides good anti-stick properties.
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).
