| description | A pipe or a supplementary pipe article comprising a polyethylene composition comprising a base resin which comprises: (A) a first ethylene homo- or copolymer fraction having an MFR2 in the range of 300 to 700 g/10 min, and (B) a second ethylene homo- or copolymer fraction, wherein fraction (A) has a lower average molecular weight than fraction (B), wherein the base resin has a density in the range of 0.945 to 0.949 kg/cm3 and an MFR5 in the range of 0.2 to 0.4 g/10 min and a comonomer content of higher than 2.0 wt.-% and a SHI(2.7/210) in the range of 55 to 100.
L'invention porte sur un tuyau ou un article de tuyau accessoire qui comprend une composition de polyéthylène incluant une résine de base. Ladite résine de base renferme : (A) une première fraction d'homo- ou copolymère de l'éthylène ayant un MFR2 se situant dans la plage de 300 à 700 g/10 min, et (B) une seconde fraction d'homo- ou copolymère de l'éthylène dans laquelle la fraction (A) a une masse moléculaire moyenne inférieure à la fraction (B), la résine de base ayant une masse volumique se situant dans la plage de 0,945 à 0,949 kg/cm3 et un MFR5 se situant dans la plage de 0,2 à 0,4 g/10 min et une teneur en comonomère de plus de 2,0 % en poids et un SHI(2,7/210) se situant dans la plage de 55 à 100. |
