Insulating and flame retardant polyamide composition for covering an electric battery interconnecting bar

Abstract

The present invention relates to a flame retarded insulating composition for covering electric battery busbars, comprising by weight: (a) from 30 to 65%, more particularly from 30 to 63.9%, in particular from 30 to 60%, of at least one semi-crystalline aliphatic polyamide, (b) from 15 to 40%, more particularly from 15 to 30%, of at least one semi-aromatic polyamide, (c) from 15 to 30%, more particularly from 20 to 25%, of at least one phosphinate flame retardant, (d) from 5 to 20%, more particularly from 5 to 15%, of at least one functionalized polyolefin, (e) from 0 to 6%, more particularly from 1 to 6%, in particular between 2 and 4%, of at least one plasticizer, (f) from 0 to 10%, more particularly 10 from 0.1 to 5%, of at least one additive, the sum of the constituents (a) to (f) being equal to 100%.
