Crosspolimeri POLIGOM G/44 EPR/EPDM
Categories:	Polymer; Thermoset; Rubber or Thermoset Elastomer (TSE)
Material Notes:	POLIGOM: is the trade-mark of our flexible crosslinkable EPR/EPDM polymer. POLIGOM G/44: chemically crosslinkable elastomer base for low voltage cable insulation and sheathing. 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 or MAC/600 P2 (flexible type). REACTION BETW EEN GRAFTING AND CATALYST: These two com pounds, separately stored, must be mixed before starting extrusion in the ratio: GRAFTING/CATALYST 94/6 Certify: HD 22, 1 EI4-EI6-EI7-EM3, VDE 0207/20 3GI3, BS 7655 RS5-GP7 Information provided by Crosspolimeri S.P.A.
