PURPOSE: Provided are a poly-1-butene resin composition and a pipe comprising the composition. More particularly, the poly-1-butene resin composition has excellent high-speed moldability into a pipe such as a cold or hot water pipe, particularly a cold or hot water supply color pipe, and the pipe comprises the composition. CONSTITUTION: The poly-1-butene resin composition comprises a poly-1-butene resin having MFR of 0.01 to 50 g/10 min, polyethylene having a viscosity-average molecular weight of 900 to 29,000 and/or polypropylene having a viscosity-average molecular weight of 900 to 29,000, and optionally, a pigment, wherein the content of the polyethylene and/or the polypropylene is in the range of 0.001 to 5 parts by weight based on 100 parts by weight of the poly-1-butene resin. A pipe, a cold or hot water pipe and a cold or hot water supply color pipe comprise the above-mentioned composition. The composition has excellent high-speed moldability into a colorless or color pipe and is favorable for application to a cold or hot water pipe, particularly a cold or hot water supply color pipe. The pipe, the cold or hot water pipe and the cold or hot water supply color pipe are excellent in productivity and their production cost can be reduced. |
