A 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 comprises 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 of the invention are excellent in productivity and their production cost can be reduced. |
