Polidan EC/51 is a flexible low density XLPE curable by moisture and consists of a silane pregrafted base compound and a catalyst masterbatch (Sioplas method).

Polidan EC/51 is characterized by excellent electrical and mechanical properties together with a good flexibility that makes it competitive in some applications as an alternative to EPR based compounds.

Its high self-crosslinking rate by ambient moisture exposure makes it particularly suitable in all cases in which crosslinking in low pressure steam or in hot water cannot be achieved.  Its high crosslinking level allows the use of Polidan EC/51 in 250°C short circuit temperature applications.

In order to prevent prescorching the pregrafted compound and the catalyst masterbatch must be stored separately and mixed only when used.
