Material Data Sheet
Material: Noryl®
Polyphenylene Oxide, ModifiedNoryl® due to its inherent chemical composition, exhibits unusually low moisture absorption. Therefore, good electrical insulating properties are realized over a wide range of humidity and temperature conditions. Chemical attack from water, most salt solutions, acids and bases is also minimal with Noryl®. The addition of glass fiber reinforcement enhances both th mechanical and thermal properties of the basic Noryl® material. This material also offers good electrical insulating properties along with long term dimensional stability.
