DESCRIPTIONNoryl® 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 PROPERTIESNoryl® 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 APPLICATIONSNoryl® 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
