                Introduction

                PEX technology is the cross-linking of polyethylene. By modifying the polymer and changing its characteristics using additives, polyethylene can be used in new, more demanding applications.
                While the improved maximum operating temperature is one of the initial attractions of cross-linking, there are other advantages in comparison with uncross-linked polyethylene:

                Reduced deformation under load (creep)
                Improved ageing resistance
                Improved chemical resistance
                Improved abrasion resistance
                Improved impact strength
                Reduced rapid crack propagation (RCP), even at low temperature
                Improved environmental stress crack resistance (ESCR)
                Outstanding resistance to slow-crack growth


                The following three methods are mainly used for cross-linking polyethylene :
                Peroxide cross-linking : PE-Xa
                Silane cross-linking : PE-Xb
                Irradiation cross-linking : PE-Xc


                The advantages of the silane process:
                Easy processing
                No special equipment required
                Outstanding mechanical properties
                High production speed
