1 Durlon 8500 Green Application A high performance compressed gasket material for use in process industries including pulp and paper, food and beverage, pharmaceutical, hydrocarbon, chemical, and refinery, as well as general industry. Developed as a quality compressed aramid- fiber gasket material for service to 700 F (371 C) or pressure to 1500 psi (10 MPa). Suitable to form a tight seal against oils, water, steam, air and many other liquids and gases. Exhibits good compressibility and recovery, excellent flexibility and cutting characteristics. A release agent on both sides ensures good anti-stick properties. Composition . Durlon 8500 Green contains high-strength aramid fibers bonded with high grade nitrile NBR synthetic rubber.
2 Fire Testing . Durlon 8500 has successfully passed a modified version of the API 607 fire test. The duration of the direct flame portion of the test is 30 minutes and the flange temperature must reach 1200 F in the first 15 minutes. The internal pressure is held at a constant 30 psig. After the flame is shut off, the fixture is immediately water quenched with an overhead water blast. Leakage must no exceed 100 ml/min. after a 6 minute cool down to successfully pass the test. Subsequent leakage testing is also performed. Typical Properties Based on 1/16" thickness Color Green Density g/cm3 (106 ). Tensile Strength across grain ASTM F 152 1800 psi ( ).
