Abstract
A polyamide composition comprising a base polyamide and an elastomer concentrate comprising: 20-80 wt % of an elastomeric aliphatic polyether having a molecular weight ranging from 400-4000 g/mol; and 80-20 wt % of a concentrate polyamide. The polyamide composition has particular uses as a cable tie and demonstrates improved cold-temperature applications while maintaining high strength, good flammability rating, and excellent processability.
