摘要
A polymer composition is provided. The polymer composition includes a polyolefin, at least 30% by weight of a thermoplastic elastomer, and a filler material. When the polymer composition is formed into an article having a longitudinal axis, the polymer composition has an average coefficient of thermal expansion along a longitudinal axis of less than or equal to 150x10-6m/mK as measured from -40C to 25C. Further, the polymer composition has an elastic modulus of less than 3000 MPa as measured using dynamic mechanical analysis (ASTM D4065), and the polymer composition has an elongation at break of greater than 200% along the longitudinal axis (measured according to ASTM D638). An article made from the polymer composition and a cable including the polymer composition are also provided.
