Durlon® 8500 Aramid-Inorganic/NBR

Application:

Our workhorse material, DURLON® 8500 is excellent in steam, natural gas, soybean processing and with new generation refrigerants. A high quality general service gasket material for use in a wide range of services in pulp and paper, food, beverage, pharmaceutical, chemical, refinery, gas pipeline and general industry. DURLON® 8500 exhibits good compressibility and recovery, excellent sealability, flexibility and cutting characteristics.

 

Composition:

DURLON® 8500 contains high-strength aramid and inorganic fibres bonded with high-grade nitrile (NBR) rubber.

 

Fire Testing:

DURLON® 8500 has successfully passed the API 6FB fire test [avg. temperature >650°C, 30 mins, 40 bar, 1 ml (inch/min.) maximum allowable leakage].

 

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).
