| DINALEN 50 is low density polyethylene containing no additives. It is primarily intended for blow and cast film extrusion while other processing techniques can be used to a lesser extent. DINALEN 50 exhibits very good draw-down with good balance of stiffness, mechanical and optical properties of extruded film. DINALEN 50 is extruded at recommended melt temperature range between 160°C and 180° C. Recommended film thickness: 0.025 to 0.060 mm. Application Thin non-slippery film of high gloss and transparency Heat shrinkable film with excellent stiffness for industrial bundling Extruded foams with physical blowing agent Small diameter pipe extrusion Wire and cable sheathing Injection moulded thick-walled products Blown packaging and other shallow objects Mixing and co-extrusion with suitable polyolefin grades&& |
