In 2021 Russian manufacturers of peroxide-crosslinked polyethylene (PEX-A) pipes plan to install twin-screw high-speed extrusion lines for PEX-A pipes, each pf which can produce up to 30 m of 16 mm diameter pipes per minute. One such line is capable of producing more than 1,000 tons of peroxide-crosslinked polyethylene per year. These lines will almost completely satisfy the domestic demand in this segment.
Pipes made of polyethylene crosslinked with peroxide are used in indoor hot and cold water supply systems, as well as in radiator and underfloor heating systems, and are popular in its "expensive" segment.
This popularity is mainly due to the fact that peroxide-crosslinked polyethylene as a raw material for pipes has a unique long-term hydrostatic strength, exceeding most types of polymers used for pipe extrusion. Pipes made from PEX-A raw materials also have good organoleptic properties - they are shiny, elastic and flexible, not prone to kinks during installation.
