    About Me

    A little about why I'm here, my background, and why technology.

    Low-density polyethylene (LDPE) is a thermoplastic made from the monomer ethylene. It was the first grade of polyethylene, LDPE produced in 1933 by Imperial Chemical Industries (ICI) using a high-pressure process via free-radical polymerization.1 Its manufacture employs the same method today. The EPA estimates 5.7% of LDPE (recycling number 4) is recycled in the United States. Read More - https://plasticranger.com/what-is-ldpe/

    LDPE is defined by a density range of 0.910–0.940 g/cm3. It is not reactive at room temperatures, except by strong oxidizing agents, and some solvents cause swelling. It can be made in a variety of ways:

    • High-pressure free-radical process
    • Solution process
    • Low-pressure process

    LDPE has numerous applications because of its low cost, flexibility, and durability. It is used in packaging (plastic bags, plastic films, geomembranes, containers including bottles, etc.), lumberyard core stock, toys, and as an inner layer in some multi-layer laminates.

    A major end use for LDPE is in film applications where it is extruded into thin sheets and used in a wide variety of applications such as:

    • Packaging film
    • Stretch film
    • Wide width film for laminates
    • Adhesive tape
    • Geomembranes

    LDPE is also used for:

    • Molded articles
    • Coated paper
    • Carpet backing
    • Wire and cable insulation
    • Pipes and fittings

    In 2013, global production capacity of LDPE was around 26.7 million tonnes per year. It is the largest-volume synthetic polymer produced in the world.
