FIELD: polymer materials. SUBSTANCE: polyethylene-based composition for pressurized transportation of liquids with standard volume mass above 940 kg/cu.m contains talk in amount below 1 wt part per 100 wt parts polyethylene. Pipes and joining parts are manufactured from composition preferably in the form of extruded granules and show good resistance against slow cracking. EFFECT: increased resistance to hydrostatic pressure and, therefore, to flowability. 9 cl, 1 tbl, 2 ex
