| description | 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. |
