METHOD AND MEANS FOR PRODUCING MOULDED PIPES WITH A MICROCELLULAR CRANIAL STRUCTURE

摘要

The invention relates to a method and means for producing moulded pipes with a microcellular cranial structure, of the type made from thermoplastic polymer having at least one foaming agent and one nucleating agent added thereto, which can be introduced into a mould and, with the application of temperature and pressure, produce a product which is suitably cooled with the aid of a second sizing mould in order to obtain an end product having a microcellular cranial structure.
