1 . | The upper service temperature is based on heat-aging tests and represents the temperature at which tensile strength and elongation would be expected to be diminished 50% after 10,000 hr thermal aging. Upper service temperatures above 150°C (302°F) may be feasible, depending on such factors as chemical exposure and support from the substrate. Particularly when considering uses of Tefzel ? 2195 above 150°C (302°F), perform preliminary testing to verify the acceptability. |
