POLIGOM : is a crosslinkable EPR/EPDM. POLIGOM G/30 CS : is a chemically crosslinkable rubber for low voltage cable insulation and sheathing. It is a conveniently grafted compound able to react in presence of moisture and of a catalyst MAC/202-203 or MAC/100 SCU (more reactive). These two compounds, separately stored, must be mixed before starting extrusion in the ratio: GRAFTING/CATALYST 95/5 Cerfity: HD221 S3 EI4-EI6, AS/NZS 3808:2000 X-90, R-E-110&& |
