Crosspolimeri GETILAN GPE/400 G Crosslinkable Polythene
Categories:	Polymer; Thermoplastic; Polyethylene (PE)
Material Notes:	GETILAN: is the trade-mark of our crosslinkable polythene. GETILAN GPE/150 LP: medium density chemically crosslinkable compound for low and medium voltage insulation, suitable also for G7. It is a conveniently grafted polythene able to react in presence of moisture and of catalyst. Normally we suggest our type MAC/202 or MAC/203 (suitable for extrusion temperature lower than 215/220 °C) REACTION BETWEEN GRAFTING AND CATALYST: These two polyethylenes, separately stored, must be mixed before starting extrusion in the ratio: GRAFTING/CATALYST 94/6 Certify: IEC 60502-1 XLPE, EPR/HEPR, CEI 2011 G7, HD 22-1 EI7 Information provided by Crosspolimeri S.P.A.
