Engineering 185°F - 300°F | Polyphenylene Oxide (PPE)


TECANYL®, due to its inherent chemical composition, exhibits unusually low moisture absorption. Therefore, good electrical insulating properties are realized over a wide range of humidity and temperature conditions. Chemical attack from water, most salt solutions, acids and bases is also minimal with TECANYL®. The addition of glass fiber reinforcement enhances both the mechanical and thermal properties of the basic TECANYL® material. Made from Noryl® EN265 resin.

  • Good electrical insulating properties
    Due to its extremely low water absorption with values as low as 0.07%, TECANYL® is an excellent electrical insulating material.
  • Long-term dimensional stability
  • Superior impact strength
    TECANYL® has a notched Izod impact strength of 3.5 ft-lbs/in.
  • TECANYL® exhibits a continuous use temperature in excess of 220°F
  • Wide range of UL flammability ratings from
    UL94 HB to UL94 V-1
  • Light weight
    TECANYL®, with a density of 0.0383 lbs/in3, can be used in applications where weight is a significant consideration.
  • Thermoformable capability
  • Possesses good hydrolytic stability

Made from Noryl EN265 resin® exhibits a broad range of outstanding properties for applications in computers and business equipment, automotive, electrical insulation, telecommunications, appliances, electronics, and many other industries.
