Tables 3.70 through 3.72 summarize the effect of one-year South Florida outdoor exposure on the electrical and mechanical properties of FEP. Little change has occurred in the dielectric breakdown strength, dielectric constant, and dissipation factor of FEP due to exposure. Tensile strength and break elongation measurements are essentially unchanged. The only decline is in the MIT flex life (ASTM D2176) of the one-year sample, which could be due to measurement error. The reason for a decrease in flex life could be the MIT method that has a high degree of uncertainty. Certainly, the other mechanical properties do not support the measured decline in the flex life.

Flex Life - Flex fatigue life is the total number of cycles that a specimen can be flexed in a prescribed manner before failure occurs. Failure is defined as physical breakdown of the specimen material. A number of methods such as MIT, Ross and De Mattia are used to measure flex life. See also Fatigue Life. [Pg.529]

There are several common flex life machines including MIT Flex, Ross Flex, and DeMattia Flex. The MIT Flex test is used to measure the abihty of plastic films to withstand fatigue from flexing. This... [Pg.10]
