Abstract:
(EN)  A polyethylene or similar used in a pipe and/or in a coupling, which has the following properties (i) to (iii). Property (i): high load melt flow rate (HLMFR (W), JIS K7210, at a temperature of 190 ℃ and with a 21.60 kg load) is in the range 5 to 35 g / 10 min. Property (ii): density is in the range 0.945 to 0.960 g/cm³. Property (iii): peak top time in isothermal crystallization at 121.5 ℃, as measured with a differential scanning calorimeter (DSC), is 360 seconds or less.
(FR)  L'invention concerne un polyéthylène et similaire utilisé au moins soit dans un tuyau soit dans un joint, et lequel satisfait les trois conditions (i) à (iii) suivantes. Condition (i): l'indice de fluidité à charge élevée (HLMFR (W), JIS K7210, à une température de 190 ℃ et pour une charge de 21,60 kg) se situe dans la plage 5 à 35 g / 10 min. Condition (ii): la masse volumique est comprise dans la plage 0,945 à 0,960 g/cm³. Condition (iii): la durée de pic dans la cristallisation isotherme à 121,5 ℃ telle que mesurée au moyen d'un calorimètre différentiel à balayage (DSC) est inférieure ou égale à 360 secondes.
(JA)  下記の特性(i)~(iii)を満足し、パイプ及び継手の少なくとも一方に用いられるポリエチレンなどによる。 特性(i):ハイロードメルトフローレート(HLMFR(W)、JIS K7210、温度190℃、荷重21.60kg)が5~35g/10分である。 特性(ii):密度が0.945~0.960g/cmである。 特性(iii):示差走査熱量計(DSC)にて測定される121.5℃での等温結晶化におけるピークトップ時間が360秒以下である。
