| Safrene® F 7740F2 High Density Polyethylene Resin is a medium molecular mass extrusion grade ideally suited to the extrusion and subsequent knitting of tapes and monofilaments typically used in agricultural pockets and shade netting. Safrene® F 7740F2 High Density Polyethylene Resin is also used for film extrusion applications where excellent roll geometry is required. As a film it exhibits an excellent barrier to moisture. Safrene® F 7740F2 High Density Polyethylene Resin contains slip and antistatic additives. Typical Applications Monofilaments Stretched tapes Films for laminating Co-extruded films Drip-bag over pouches&& |
