Abstract

A thermoplastic elastomer composition and method of making the thermoplastic elastomer are disclosed. The thermoplastic elastomer may comprise a polymer blend. The polymer bland may comprise a non-crosslinked elastomer, oil, polyethylene, and antioxidant. The oil may be from about 15 wt. % to about 50 wt. % oil. The polyethylene may be from about 3 wt. % to about 30 wt. %. The antioxidant may be from about 0 to about 0.5 wt. %.
