Noryl® PPO

Noryl® PPO

Noryl EN-265 PPO sheet and Rod

Noryl – PPO – Polyphenylene Oxide

Sheet and Rod


Noryl® PPO material is used frequently in fluid handling applications due to the very low moisture absorption.

Noryl is similar to Acetal and P.E.T. but carries a better UL rating.

Noryl rods and Noryl sheets are in stock and available in a number of sizes in black. It is great for electrical applications requiring high die-electric strength. Noryl is a trade name of Sabic Plastics (formerly GE Plastics).

Noryl is a High Tech Performance Plastic.

Why you should use Noryl®:

  • It has excellent electrical properties
  • It has excellent Fire Retardant Rating
  • Has extremely low water absorption
  • It is vacuum formable, machinable and bondable
  • Has good temperature resistance
  • Readily available in Sheet or Rod
  • Noryl is ITAR compliant, and Noryl is RoHS compliant

Noryl PPO Machined Nozzle

This material is a strong engineering plastic with excellent mechanical, thermal and electrical properties. One of the lowest moisture absorption material, with very low thermal expansion. PPO also retains most of its flexural and tensile strength as well as its resistance to creep at elevated temperatures.

Frequently used in:

  • Fluid Handling, Pump and Valve – Low Moisture Parts
  • Electrical Housings, Cases and Components
  • Instrumentation and Semiconductor Components
  • High Continuous Temperature Environments (185 degrees F ; 265 degrees F)
  • Flame Retardant Parts Needing UL-94 V-1 (at .058″ thickness)

Noryl is an easy to machine performance plastic

Noryl versus PPO

What is the difference between Noryl and PPO (or Modified PPO)?

Noryl® is a trade name for Sabic Plastics (formerly GE Plastics) for their Modified PPO (Modified PolyPhenyleneOxide). Sabic is the world leader in engineering and mechanical plastic resins.

This resin is a remarkably versatile material. PPO exhibits unusually low moisture absorption and great machinability. Noryl® is an excellent choice for water filtration and fluid handling parts. Noryl has excellent impact resistance, long term dimensional stability and is light weight. Noryl® has exceptional electrical properties (properties boosted by lack of water absorption). It can be thermoformed and machined to tight tolerances. It carries a UL flammability rating between UL 94-HB to UL 94 V-1. The primary specification covering PPO (Noryl®) is ASTM-D-4349.

Sabic Noryl is available in two standard unfilled varieties, EN-185 and EN-265. The number indicates the heat deflection temperature of the material. This material is easy to machine, holds tolerances well, and is great for water immersion applications. A complete data sheet is found hereNoryl EN-265 machined nozzle.

We stock this material in both sheet and rod. The standard natural color for Noryl is opaque Black and is stocked as the EN-265 grade of resin. Noryl® is also available as a glass filled material which enhances both the mechanical and thermal properties of the resin. Chemical attack from water, most salt solutions, acids and bases is also minimal with Noryl®.

Materials with similar physical properties are ABS, Acetal Copolymer, PET and PBT (Polyester) and Nylon.
