Chem Polymer’s 25% glass fiber-reinforced nylon 6 compound provides injection molders with an alternative to halogenated flame retardant (FR) formulations while meeting stringent requirements for flame retardance. Chemlon 225 GVNH has a UL 94 flammability listing of V0 at thicknesses down to 0.032 in (0.8 mm). According to the company, its comparative tracking index of 600 V is more than double that of a comparable compound with a halogenated (typically brominated) FR formulation. Providing electrical performance in automotive applications, the compound is also 14% less dense, yielding lighter parts. Chemlon 225 GVNH is in commercial use for the housing of an air filter used in a vehicle engine compartment (pictured).
