Полиэтилен низкого давления PS 380-30/302
для производства труб

TIPELIN PS 380-30/302 is a black compound, medium density polyethylene co-polymer (with hexen-1 as co-monomer) grade for gas and drinking water pipes, injection moulded fittings, extruded sheets, profiles and geomembrane. TIPELIN PS 380-30/302 shows very excellent environmental stress crack resistance (ESCR) and long service life. ( MRS 8, PE 80 )
