Summary: | To provide an ethylene ionomer for tubes that achieves a good balance of flexibility, wear resistance, and transparency and a molding thereof.SOLUTION: An ethylene ionomer for tubes contains an ionomer in which a phase angle δ in an absolute value G*=0.1 MPa of a complex elastic modulus measured with a rotary rheometer is 50-75 degrees and which is substantially linear. In the ionomer, a melt flow rate (MFR) at temperature 190°C and load 2.16 kg is 0.1-15 g/10 min; a tensile elasticity is 20-350 MPa; an amount of wear in a wear test is less than 10 mg; and a haze is 0.1-30%.SELECTED DRAWING: None
