Cross-linked polyethylene (PEX-a) pipes are the modern generation of polymer pipelines. XLPE is best suited for hot and cold water, radiator and underfloor heating applications. PEX-a has been used in engineering systems for over forty years. The use of XLPE pipes around the world is growing at an annual rate of 6.7%.

PEX-a is a thermosetting material, and the XLPE pipe has a three-dimensional mesh structure with a dense base and excellent performance.
