Low density polyethylene (LDPE)
Polyethylene is a thermoplastic polymer resulting from the polymerization of ethylene monomer. Its macro-molecular structure is linear, with a smaller or larger number of ramifications. Polyethylene produced by various technologies are different between them by values of some features such as: molecular mass, degree of ramification, crystallinity, density, mechanical properties, thermal properties, etc.
Low density polyethylene has a high resistance to impact, a modest structural strength and a good resistance to many chemicals attack. It is processed mainly by centrifugation, blowing and injection.
LDPE takes the form of transparent, opaque or colored granules and has a degree of crystallinity between 40 and 50%.
Advantages
- very low cost;
