End Product Performances

It is well known that crosslinking of a polymer induces significant changes on its performance. The primary reason for crosslinking polyethylene is to raise the thermal stability of the material under load. Environmental stress crack resistance (ESCR) and resistance to slow crack growth are also significantly improved.

Table 1 summarizes the properties changes raised by crosslinking of PE.

(*) Using Silane Technology results in better impact resistance and tensile strength than with Peroxide Crosslinking

Compared to other crosslinking technologies, the use of Silane Technology provide materials with better heat ageing
