Application:
Durlon® 8700 is a high performance gasket material for use in processes requiring a neoprene (CR) bonded sheet such as refrigeration services. This product has excellent resistance to ozone, oils, non-aromatic solvents and many refrigerants.
Composition:
Durlon® 8700 contains high-strength aramid and inorganic fibres bonded with high-grade neoprene 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).
