Effect of Temperature and Frequency on Dielectric Properties
Because of the inherent thermal stability of the polyphenylene sulfide (PPS) polymer, the dielectric properties of Ryton® PPS compounds remain stable over a wide range of temperatures and frequencies. The data shown below were generated using identical specimens in accordance with ASTM D150 within a controlled temperature chamber.
