Polyphenylene Oxide (PPO)

Commonly known as Noryl®

Noryl® modified PPO is a strong engineering plastic with outstanding mechanical, thermal, and electrical properties. Low moisture absorption and low thermal expansion make Noryl® one of the most dimensionally stable thermoplastics available. Noryl® 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. Noryl® is often selected for fluid handling applications since it has low moisture absorption and excellent strength and stiffness. Noryl® is easy to fabricate, paint, and glue.
