Abstract
The present invention relates to a high-density ethylene-based polymer and a pipe using the same, the high-density ethylene-based polymer including: an ethylene homopolymer; or a copolymer of ethylene and at least one comonomer selected from the group consisting of an α-olefin, a cyclic olefin and linear, branched and cyclic dienes. The pipe using the high-density ethylene-based polymer of the present invention has more superior strain hardening than a conventional polyethylene resin pipe, and thus has excellent long-term pressure resistance characteristics and processability.
