Abstract

Eleven materials were evaluated for oxygen compatibility using the following test methods: heat of combustion (ASTM D 2015), liquid oxygen impact (ASTM D 2512), pneumatic impact (ASTM G 74), gaseous mechanical impact (ASTM G 86), autogenous ignition temperature by pressurized differential scanning calorimeter, and the determination of the 50 percent reaction level in liquid oxygen using silicon carbide as a reaction enhancer. The eleven materials evaluated were: Teflon^® TFE, Vespel^® SP-21, Krytox^® 240AC, Viton^® PLV5010B, Fluorel^® E2160, Kel F^® 81, Fluorogold^®, Fluorogreen^® E-600, Rulon^® A, Garlock^® 8573, nylon 6/6.
