Polyphenylene Oxide Characteristics

Polyphenylene oxide, made under the Noryl® brand, is easily machined thermoplastic that is a smart choice for many applications. Noryl® is a high-performance, cost-effective material with good impact resistance and low moisture absorption. NOTE: This material is not resistant to petroleum products.

Noryl® offers dimensional stability and strength even at high temperatures (up to 230 degrees Fahrenheit continuous use) and meets UL 94V-O requirements. It also offers excellent electrical properties over a wide frequency range. Characteristics include:

  • here to help 200Low moisture absorption
  • Heat resistant to 265° F
  • Cost-effective
  • Good electrical insulating properties
  • Long-term dimensional stability
  • Superior impact strength

Applications for Noryl®

  • Liquid handling equipment
  • Telecommunications
  • Appliances
  • Electrical insulators and components
  • Medical components
