Phenylene Oxide-Based Resin—General Electric

NORYL resins are especially noted for their outstanding hydrolytic stability. The water absorption rate of all NORYL resins, both at room temperature and at elevated temperatures, are among the lowest of any engineering thermoplastic, which contributes to the retention of properties and dimensional stability in the presence of water, high humidity and even steam environments. In addition, NORYL resins are also virtually unaffected by most aqueous solutions, detergents, acids, and bases.
