NUOVI CONDOTTI IN MATERIALE POLIMERICO

摘要

A pipe (1) constituted by an inner wall (2) produced with a first high-performance thermoplastic polymeric material having a distortion temperature under load in accordance with standard HDT-A ISO75 of at least 275 DEG C and an outer wall (3) produced from a second thermoplastic material belonging to the same family of chemical polymers as the high-performance thermoplastic material and coinjected therewith for production of the pipe itself.
