Polyphenylene oxide dielectric properties

D. Electrical Properties Because of the water-resistant nature and low moisture absorption levels, most polyphenylene oxide alloys present good electrical properties over a wide range of humidity and temperature ranges. PPO has a low dielectric constant of 2.58 (at 23°C 60 Hz), a low dissipation factor of 0.00035 and a high glass transition temperature (T ) of approximately 212°C, which are suitable materials for insulating matrices for electrical and electronic devices.

Glass-reinforced modified polyphenylene oxide is a tough, rigid thermoplastic with excellent dielectric properties, high moisture resistance, and dimensional stability. [Pg.80]

Noryl n Poly(phenylene oxide) Trade name for a family of blends of polyphenylene oxide (PPO) with much less costly styrenic polymers. These blends have the processability, low water absorption, and good dielectric properties associated with polystyrene, while the PPO contributes heat resistance. Glass-reinforced grades are available. Manufactured by General Electric, U.S. [Pg.490]
