Noryl® (polyphenylylene oxide, modified) Noryl®, 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. Chemical attack from water, most salt solutions, acids, and bases is also minimal with Noryl®. The addition of glass fiber reinforcement enhances both the mechanical and thermal properties of the basic Noryl® material.
