Abstract
Embodiments of the disclosure relate to a polymer composition. The polymer composition includes from 0% to 80% by weight of a polyolefin component and from 20% to 100% by weight of a thermoplastic elastomer component. The polymer composition has an elastic modulus of less than 1500 MPa at −40° C. as measured using dynamic mechanical analysis according to ASTM D4065. Further, the polymer composition has a coefficient of thermal expansion as averaged over the temperature range of −40° C. to 25° C. of more than 120×10/K when measured according to ASTM E831, and the polymer composition has a thermal contraction stress of no more than 4.0 MPa at −40° C. as measured using dynamic mechanical analysis. Additionally, embodiments of an optical fiber cable having a cable jacket made of the polymeric composition are disclosed herein.
