Noryl® PPO, Modified Polyphenylene oxide, Extruded - is a strong engineering plastic with outstanding mechanical, thermal and electrical properties. Very 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 and is easily machined, fabricated, painted and glued.
