Crosspolimeri POLIGOM G/42 EPR/HEPR/EPDM
Categories:	Polymer; Thermoset; Rubber or Thermoset Elastomer (TSE)
Material Notes:	POLIGOMN: is the trade mark of our crosslinkable EPR/HEPR/EPDM compound ( phthalate plasticizers free ). POLIGOM G/42: halogen free 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/400 PS or MAC/100 SCU (more reactive). FOR SOLAR CABLES INSULATION WE SUGGEST TO USE CATALYST MAC/520 PSL at 7/10%. 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- G7, BS7655 GP4-GP5-GP6-GP7, CEI 2011 G7, EN 50620 EVI-2, IEC 60502 EPR-HEPR Information provided by Crosspolimeri S.P.A.
