Noryl n Poly(phenylene oxide) Trade name for a family of blends of polyphenylene oxide (PPO) with much less costly styrenic polymers. These blends have the processability, low water absorption, and good dielectric properties associated with polystyrene, while the PPO contributes heat resistance. Glass-reinforced grades are available. Manufactured by General Electric, U.S. 

Polyphenylene oxide (Noryl from GE) and polyphenylene sulfide (Ryton from Phillips) are used as high-temperature engineering plastics. Polyphenyl ether sulfones are manufactured by a number of companies under a variety of trade names including 720P, 220P by ICI and RADEL by Union Carbide. They are generally used as injection-moldable thermoplastics and in the adhesive and composite industry. 

PS-modified polyphenylene oxide is produced by GE plastics and marketed under the trade name Noryl. Applications include UL 94 V-0 flame retardant [3] PCB enclosures and glass-fibre filled self-extinguishing UL 94 V-1 relay bases. The latter application permits 600 V operation with an operating temperature of 110 °C and a short-term tolerance of 135 °C.
