POLIGOM is the trade-mark of our crosslinkable EPDM compound (phthalate plasticizers free).
POLIGOM R/75 is a chemically crosslinkable rubber for low voltage cable insulation and sheathing suitable for G7. It is a conveniently grafted compound able to react in presence of moisture and of a catalyst.
We normally suggest our catalyst type MAC/202 or MAC/203.

FOR SOLAR CABLES INSULATION WE SUGGEST TO USE CATALYST MAC/520 at 7-7,5 %.

REACTION BETWEEN GRAFTING AND CATALYST:
These two compounds, separately stored, must be mixed before starting extrusion in the ratio:
GRAFTING/CATALYST 94/6

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: three or five days are enough.
