- Description
-
Low-Density Polyethylene is a thermoplastic made with high-pressure non-catalytic process from the monomer ethylene with a density range of 917–930 kg/m3.
The free-radical polymerization process results in a highly branched molecular structure, in its turn responsible for the low density of the product. This branching reduces intermolecular forces, making LDPE less crystalline and more flexible compared to other polyethylene types like HDPE.
LDPE has SPI recycling code nr. 4.
