Polyphenylene Sulfide(PPS) Film Torelina*

Electrical Properties

(1) Dielectric Properties
The dielectric constant of Torelina* is 3.0, and it is exceptionally stable for a wide range of temperature and frequency variations. Fig. E6 shows the temperature dependence of dielectric constant in Torelina*, and Fig E7 shows the frequency dependence.

(2)Dissipation Factor
The dissipation factor(tan δ) of Torelina is exceptionally small, very close to that of polypropylene film, when its dielectric constant is taken into account. At temperatures below 120°C , the dissipation factor is very consistent over temperature or frequency variations. Fig.E8 shows the temperature dependence of the dissipation factor in Torelina*, and Fig.E9, its frequency dependence.
