摘要: The present invention relates to flame-retardant polyamide compositions. In various aspects, the present invention provides a flame-retardant polyamide composition including a polyamide that is about 30 wt % to about 99 wt % of the composition. The polyamide has a relative viscosity (RV) of ≥20 to ≤33 as measured as an 8.4 wt % solution in 90% formic acid. The composition also includes one or more flame-retardant additives. Various aspects of the present invention provide compositions having enhanced flame-retardant properties as compared to corresponding compositions including the same or greater concentration of flame-retardant additive but using a polyamide that has an RV that is 33.
