High-pressure performance polyethylene (HPP/LDPE)

Polyethylene produced under high pressure is called high pressure performance polyethylene (HPP) or low-density polyethylene (LDPE). Low-density polyethylene (LDPE) is a PE with a relatively highly branched macromolecule and low density (0,916-0,935 g/cm³). The process of its manufacturing takes place under very high pressure from 100 to 300 MPa and the temperature of 100-300 °C; therefore, it is specified the same way as high-pressure performance polyethylene (HPP).

The applications of LDPE:

LDPE occupies the leading position in the world in terms of production and application. LDPE was first used in electrical industry, mainly as an insulating material for submarine cables and later on for radars. LDPE crystallinity usually varies in the range of 55-70% (compared to 75-90% of HDPE).

The applications of LDPE are:

• Film extrusion;
• Cable production;
• Injection molding of plastics;
• Blow molding.
