Abstract

Настоящее изобретение относится к способу производства труб, содержащих по меньшей мере один слой, выполненный из полипропиленовой композиции, включающей основную смолу бета-нуклеированного полипропилена, причем способ включает стадии: а) экструзии полипропиленовой композиции при температуре выше 200°С, б) последующего охлаждения экструдированного продукта в охлаждающей среде при температуре выше 5°С, и в) последующего отжига экструдированного продукта в среде отжига при температуре не менее температуры охлаждающей среды на стадии б), а также к трубам, содержащим по меньшей мере один слой, выполненный из композиции пропиленового полимера, причем средняя величина бета-кристалличности слоя трубы βвыше или равна 20%.
