Abstract: Provided are an ethylene-based polymer having excellent long-term pressure resistance characteristics and a pipe using the ethylene-based polymer. The ethylene-based polymer satisfies the balance of mechanical characteristics and excellent molding processability, as compared with a conventional ethylene-based polymer. Also provided are an ethylene-based polymer having a wide molecular weight distribution and a small lamellar thickness, thereby increasing tie molecules and obtaining excellent long-term pressure resistance characteristics, and a pipe using the same.
