What Is Noryl?

23 Aug



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.

    I urgently require a sample of the “NORYL injection moulding compound”. Grade unknown, must not cause any sinking on the moulded item and blemishes at the injection points.
    Application is: To manufacture a sliding window frame in the automotive industry. Shrinkage 0,7% and must be UV resistant.

    Hi; Was interested in this because i was reading about making hydrogen you said you were using this for electrodes and it didn’t get used up so fast as metal electrodes .in electrolisis’I’m hoping you solve the problem of making hydrogen to run cars on hydrogen.Hydrogen on demand and the electrodes last for a long time .I can understand the metal ones being used up too quick.I’m 95 yrs old and hope you get the hydrogen problem solved so i can run my car on water .Be fore i,m 100.Been a mechanic all my life I still drive my red Intrepid dodge.Keep trying .Les Cramer

    Noryl will crack in less than 24 hours when exposed to any oil, vegetable or mineral.
