ASCEND Vydyne PA66
Flame-resistant polyamide 66 and 66/6 co-polymers resins designed for V0 flame resistance and improved electrical insulating properties.


Ignition Resistant PA66 M344 Series


Vydyne® PA66 M344 resins are ignition resistant Nylon 66 resins with UL 94V-0 and UL 94-5VA flammability rating. Available in off-white or black. Lubricated for machine feed and easy mold release. Vydyne PA66 M344 resins are modified with halogenated and other ignition resistant additives to provide users a product that meets Underwriter Laboratories (UL) 94V-0 flammability classification down to thicknesses of 0.017 inches and 94-5VA down to 0.080 inches in thickness.


Ignition resistant additives generally reduce toughness and ductility when compared to general purpose, unreinforced 66 type nylon; however, Vydyne PA66 M344 resin has been formulated to minimize such loss in ductility. Vydyne PA66 M344 generally yields more ductile parts than many other nylon and non-nylon (UL) 94V-0 plastic materials in many commercial applications.


Vydyne PA66 M344 have a comparatively low specific gravity for an improved ignition resistant 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 PA66 M344 resins are essentially equivalent to that of general purpose Nylon 66 resins, which are commonly used in many electrical/electronic components and other parts requiring a UL 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 PA66 M344, eliminating the delay and costs involved in retooling.


Typical Applications/End Uses:
The combination of flammability characteristics, engineering thermoplastic properties, and retention of electrical and physical properties when exposed to heat in service make Vydyne PA66 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.
