| 摘要 |
<p>The present invention relates to a pipe consisting of a polyethylene composition which comprises - a base resin, comprising €¢ a first ethylene homo- or copolymer (A): and €¢ a second ethylene copolymer (B); and the polyethylene composition further comprises - a phenol-type stabilizer (C); and - a phenol-type stabilizer (D); whereby stabilizers (C) and (D) are different. The present invention is furthermore directed to the use of - a phenol-type stabilizer (C); and - a phenol-type stabilizer (D); whereby stabilizers (C) and (D) are different and, optionally, - a further stabilizer (E) selected from – phosphorous containing stabilizer (E1); – sulphur containing stabilizers (E2); – nitrogen containing stabilizers (E3); and/or – mixtures thereof; for increasing the slow crack growth resistance of pipes.</p> |
