Polidiemme G/220 is a high modulus EPR based compound crosslinkable by moisture; it consist of a silane pregrafted base compound and a catalyst masterbatch (Sioplas method).  It can offer mechanical and electrical properties suitable for low voltage power cable insulation in a wide range of applications, including "high modulus" requirements.

Polidiemme G/220 complies with CEI 20.11 G7 type and Cenelec HD 603 S1 (1994) DIH 1 type and IEC 60502.1 HEPR Type Standards.

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