Abstract

Disclosed is a thermoplastic elastomer composition comprising (i) about 10-60 wt % of at least one aliphatic polyamide; (ii) about 0.8-15 wt % of at least one graft-modified ethylene-olefin elastomeric copolymer; (iii) about 0.8-15 wt % of at least one graft-modified ethylene-propylene elastomeric copolymer, and (iv) about 35-85 wt % of at least one polyether-ester-amide block copolymer having a shore D of about 50-60 (as measured in accordance with ASTM D2240), with the total wt % of all components in the composition totaling to 100 wt %. Further disclosed herein is an article made from the thermoplastic elastomer composition disclosed above.
