8700 Aramid-Inorganic/CR

COMPRESSED SHEET GASKET MATERIAL

ASTM F104 F712330-A9B5E45K5L153M5
8700-786317-edited.png

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 fibers 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).

Note: ASTM properties based on 1/16" sheet thickness except ASTM F38, which is based on 1/32" sheet thickness. This is a general guide only and should not be the sole means of accepting or rejecting this material. The data listed here falls within the normal range of product properties but should not be used to establish specification limits nor used alone as the basis of design.

Warning: Durlon® gasket materials should never be recommended when both the temperature and the pressure are at the maximums listed. Properties and applications shown are typical. No application should be undertaken by anyone without independent study and evaluation for suitability. Never use more than one gasket in one flange joint, and never reuse a gasket. Improper use or gasket selection could cause property damage and/or serious personal injury. The data reported is a compilation of field testing, field service reports and/or in-house testing.
