Vydyne® M344 Series

Vydyne® 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  M344 resins are modififi ed with halogenated and other ignition  resistant additives to provide users a product that meets  Underwriter Laboratories (UL) 94V-0 flfl ammability classififi cation  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  M344 resin has been formulated to minimize such loss in ductility. Vydyne  M344 generally yields more ductile parts than many other nylon and nonnylon (UL) 94V-0 plastic materials in many commercial applications. 

Vydyne M344 have a comparatively low specififi c 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 specififi c gravity. 

Mold shrinkage of Vydyne 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  flfl ammability 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 retooling.
