Huliot Pexroma crosslinked high-density polyethylene pipe is produced by IR/Peroxide method. Crosslinking is a process which transforms the chemical structure in such a way that the polymer chains are linked within themselves into a three-dimensional network through chemical connections. The result is a flexible thermoset polymer with improved mechanical, thermal and chemical properties. The crosslinked polymeric structure makes dissolution impossible, unless its structure is previously destroyed. It is a PE-Xa pipe with thermal-elastic memory, a greater flexibility that avoids kinking, thus avoiding the risk of bottlenecks which reduce the flow, and allows the optimization of the installation process.Â
