Noryl
What is Noryl?
Noryl is a modified Polyphenylene Oxide developed by GE Plastics in 1966. Noryl EN265 is stocked and sold by Polymer Plastics. This grade offers the flame retardance advantage over other grades of Noryl and has a UL94 V-1 rating with a continuous use temperature of 105 degrees.
Noryl has good high and low temperature performance with a range from -40 degrees F to 265 degrees F. Because of its stability under load, high impact and mechanical strength, low water absorption, excellent electrical properties, and food flammability ratings, Noryl set itself apart from other materials.
It is available in a wide range of sizes in rod, sheet, and custom profiles. Modified Noryl is available in both unfilled and glass filled formulations.
Outstanding ease of fabrication in machining, thermoforming, bonding, or ultrasonic sealing, makes it a favorite of plastic fabricators. However, because Noryl is attacked by petroleum products, coolants and cutting oils containing petroleum should not be used. Because of this limitation, Noryl should not be specified for parts which may come in contact with petroleum products during normal use.
• Noryl EN265 (Black), contains a self-extinguishing additive.
• GFN3 (30% glass-filled) (Standard Color Grey)
• SE1 GFN3 (30% glass-filled with self-extinguishing additive) (Standard Grey).
