Noryl (PPO)

Noryl (PPO)

The NORYL family of modified resins consists of amorphous blends of polyphenylene oxides (PPO) or polyphenylene ether (PPE) resins with polystyrene. They combine the inherent benefits of PPE resin (affordable high heat resistance, good electrical insulation properties, excellent hydrolytic stability and the ability to use non-halogen fire retardant packages), with excellent dimensional stability, good processability and low density. Noryl® modified PPO is an engineering thermoplastic with high dielectric strength, a low coefficient of thermal expansion, and low moisture absorption which make it an excellent choice for electrical applications that require machining to tight tolerances. FDA compliant grades of Noryl® available.

They were originally developed in 1966 by General Electric Plastics (now owned by SABIC). NORYL is a registered trademark of SABIC Innovative Plastics IP B.V.
