Materials: Flame-Retardant Nylon 66 for Unattended Appliance Connectors
Ascend’s newest grade sports the highest possible glow wire ignition temperature rating.
An unreinforced, flame retardant nylon 66 compound for use in unattended appliance electrical connectors is the latest addition to a broad line of specialty nylon 66 compounds from Houston-based Ascend Performance Materials, now the world’s largest fully-integrated nylon 66 producer.
Vydyne FR350J reportedly sports a “best-in-class” glow-wire ignition temperature (GWIT) of 960 C at all thicknesses up to 3 mm. Molded parts have achieved glow-wire end-product test values of 750 C at all thicknesses. The material also achieves PLC 0 ratings in hot-wire ignition (HWI) and high-amp arc-ignition (HAI) tests according to UL 746A. In addition, the compound carries an RTI electrical rating of 130 C and UL 94V-0 rating down to 0.4 mm.
Vydyne FR350J also boasts superior melt flow and requires lower pressure to fill molds. The compound has a wide processing window and is color stable for natural and colorable applications. The FR additive package is said to exhibit low corrosion for improved electrical contact performance.
The degree to which molded parts shrink as they cool is largely dependent upon the composition of the material being processed.
The U.S. is catching up with Europe and Asia in exploring the potential of biodegradable polyesters in flexible and rigid packaging. Because of their cost, these resins often find use in blends with other degradable materials.
Plastics weigh in with added design freedom and environmental friendliness—especially when the alternative is lead.
