FLAME-RETARDANT POLYAMIDE MOLDING COMPOUNDS

Abstract

Flame-retardant polyamide molding compound, particularly for railway applications, comprising, preferably consisting of: A 34-88 wt% semicrystalline aliphatic polyamide with a C / N ratio of at least 8; B 6-21 wt% flame retardant consisting of: B1 50-100 wt% of at least one metal phosphinate; B2 0-50 wt% of at least one flame-retardant synergist and / or at least one flame retardant containing nitrogen and phosphorus; the sum of components B1 and B2 resulting in 100 wt% of component B; C 1-10 wt% graphite; D 0-25 wt% polyamide elastomer; E 0-10 wt% plasticizer; F 0-10 wt% polyolefin; G 0-5 wt% additives, other than A to F; being the sum of the weight proportions of components D to F from 5 to 30% by weight, with respect to the sum of the weight percentages of components A to G, and adding the weight proportions of components A to G 100% by weight.
