Vydyne® M344 resins are ignition resistant nylon 6,6 resins with UL 94V-0 and UL 94-5VA flammability rating. Lubricated for machine feed and easy mold release. Vydyne® M344 resins are modified with halogenated and other flame retardant additives to provide users a product which meets Underwriter Laboratories (U.L.) 94V-0 flammability classification down to thicknesses of 0.017 inches and 94-5VA down to 0.080 inches in thickness. Also available in black as Vydyne® M344 BLK.
Flame retardant additives generally reduce toughness and ductility when compared to general purpose, unreinforced nylon 6,6, but Vydyne® M344 resin has been formulated to minimize such loss in ductility. Vydyne® M344 generally yields more ductile parts than many other nylon and non-nylon (U.L.) 94V-0 plastic materials in many commercial applications.
Vydyne® M344 resins have a comparatively low specific gravity for an improved flame retardant resin. Meaningful economic comparisons of molding materials must be based on cost per cubic inch, which is reduced by lowered specific gravity.
Mold shrinkage of Vydyne® M344 resins are essentially equivalent to that of general purpose nylon 6,6 resins, which are commonly used in many electrical/electronic components and other parts requiring a U.L. 94V-2 flammability rating. Thus, existing tooling for 94V-2 nylon parts can usually be used to produce 94V-0 or 94-5VA parts from Vydyne® M344, eliminating the delay and costs involved in re-tooling.
Vydyne® M344 applications
The combination of flammability characteristics, engineering thermoplastic properties and retention of electrical and physical properties when exposed to heat in service make Vydyne® M344 resins ideal for applications in the appliance and electrical/electronic industries. Typical applications include connectors, terminal blocks, housings, circuit board standoffs, clips, clamps, fasteners, switch components and many other industrial parts.
