POLIGOM : is the trade mark of our crosslinkable EPDM compound ( phthalate plasticizers free ). POLIGOM G/42 : chemically crosslinkable elastomer 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/100 SCU. REACTION BETWEEN GRAFTING AND CATALYST: These two compounds, separately stored, must be mixed before starting extrusion in the ratio: GRAFTING/CATALYST 94/6 Certify : EN 50363-0 G7,BS 7655 GP4-GP5-GP6-GP7,HD 22.1 EI7 |

| 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. |
