Kunlun and SINOPEC Factory direct supply LDPE granules LDPE has a very good performance, especially the insulation dielectric strength is high so that it is very suitable for wire and cable. Medium to high molecular weight grades has excellent impact resistance, even at room temperature under 40 flow temperature.
Polyethylene LDPE has a high degree of short and long-chain branching. It is one of the most simplest and common polymers. It has, therefore, fewer strong intermolecular forces as the instantaneous dipole inducted-dipole attraction is less. This results in 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.
