Abstract

Описано изделие, труба из полимерного микроспенного материала, с ударной прочностью, измерянной при 0 °С, которая превышает 100 % и представляет до 400 % от ударной прочности, которая требуется европейскими нормами для трубы таких же размеров и основного материала в невспененном состоянии. Также описаны способы изготовления такой трубы. Кроме того, описана головка (1) для экструдера, который имеет перед своей щелью (2) канал (3), который суживается к щели по углу альфа, который составляет от 10 до 180°, преимущественно от 10 до 90°. Дополнительно описан экструдер, который включает головку согласно изобретению.
