Noryl is an easily machined plastic

Noryl® (Polyphenylene Oxide)

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

Characteristics

This easily machined plastic is a smart choice for many applications. Noryl® is a high-performance, cost-effective material with good impact resistance and low moisture absorption. Though it is important to note that it 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.

Applications

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