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. |

| 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. |
