Norylux modified PPO is a strong engineering plastic with outstanding mechanical, thermal, and electrical properties. Low moisture absorption and low thermal expansion make Norylux one of the most dimensionally stable thermoplastics available. Norylux is widely used for electrical housings and structural components since it has excellent insulating properties, flame resistance, and dimensional stability over a wide range of service temperatures. Norylux is often selected for fluid handling applications since it has low moisture absorption and excellent strength and stiffness. Norylux is easy to fabricate, paint, and glue.

The following physical property information is based on typical values of the base modified polyphenylene oxide resin.
