CROSS-LINKED POLYETHYLENE PIPE

摘要

A cross-linked polyethylene pipe comprising an ethylene polymer with a density of at least 948 kg/m3 obtained by polymerisation with a single-site catalyst and having a shear thinning index SHI2.7/210 of less than 10; and wherein said pipe has a pressure test at 4.8 MPa and 95° C. of at least 500 h and at 12.4 MPa and 20° C. of at least 500 h.
