|Low Density Polyethylene (LDPE) is defined by a density range of 0.910–0.940 g/cm3. LDPE has a high degree of short and long chain branching, which means that the chains do not pack into the crystal structure as well. It has, therefore, less strong intermolecular forces as the instantaneous-dipole induced-dipole attraction is less. This results in a lower tensile strength and increased ductility. LDPE is created by free radical polymerization. The high degree of branching with long chains gives molten LDPE unique and desirable flow properties. LDPE is used for both rigid containers and Plastic film applications such as Plastic bags and film wrap.|
Apex GB have over 20 years experience in manufacturing Plastic & Rubber Extrusions, Extruded Profiles and Tubing. We're quite rightfully proud of our reputation for consistently meeting the needs of customers over that time. Because we've remained small and focussed we've also remained more attentitive, more cost effective and more responsive than larger manufacturers.
