POLIGOM : is the trade-mark of our crosslinkable EPDM/EPR/HEPR compound.

POLIGOM R/75 G : chemically crosslinkable rubber suitable for sheathing and G 7,G 21 and TUV insulation extrusion.
It is a conveniently grafted compound able to react in presence of
moisture and of a catalyst.
We normally suggest our catalyst type MAC/203 HG.

REACTION BETWEEN GRAFTING AND CATALYST:
These two compounds, separately stored, must be mixed before starting extrusion in the ratio:
GRAFTING/CATALYST 95/5.

Certify : CEI 2011 G7,IEC 60502-1 HEPR, IMQ G21,TUV.

Extrusion instructions
Crosslinking of the finished product is obtained by: Immersion of the bobbin in hot water at 85/90 °C for two hours (up to 3 mm thickness) Steam treatment at 0,15 bar for 5/6 hours. -Practically we suggest air crosslinking at natural temperatures and moisture: six or 10 days are enough.No detrimental effects on crosslinking properties and capability of POLIGOM R/75 in presence of Mastebatch colours, black included.We suggest to dry masterbatch before using expecially black color.
