NORYL® modified PPO is a strong, tough 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.
