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 non-nylon (UL) 94V-0 plastic materials in many commercial applications.
Vydyne 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 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 M344, eliminating the delay and costs involved in retooling.
