DESCRIPTION
Noryl® modified PPO (Polyphenylene Oxide - Styrene) is an alloy of PPO and styrene. Due to its inherent chemical composition, Noryl® exhibits unusually low moisture absorption, providing excellent insulating properties and dimensional stability over a wide range of humidity and temperature.

KEY PROPERTIES
Noryl® has good electrical insulating properties and long-term dimensional stability due to low moisture absorption. It also has superior impact strength, is light-weight, and is hydrolytically stable. It may be used continuously at temperatures in excess of 220°F. Standard material color is black. For enhanced mechanical and thermal performance, glass fiber reinforcement may be added to Noryl® -- this material is grey in color.

NOTE: Only some selected Noryl® grades offer FDA compliant.

Because of its alloy matrix composition, Noryl® is also one of the few non-metallic materials which can be readily electroplated (after an electroless plating surface has been applied using a selective etching process).

TYPICAL APPLICATIONS
Noryl® is an exhibits a broad range of outstanding properties for applications in: • computers   • business machine housings   • automotive coil forms and instrument parts   • electrical insulation   • telecommunications   • appliances   • electronics   • water softener valves   • water pump components   • surgical instruments   • vaporizer and scrubber parts   • plated and vacuum metallized parts
