  • Our take on the Plastazote LD45 Closed Cell PE Foam Sheet

    Plastazote LD45 is a closed-cell, cross-linked polyethylene foam sheet supplied as a 2000 x 1000 mm sheet. The nitrogen cells inside the polyethylene make it lightweight, odorless, water-resistant and buoyant, and give it strong resistance to oils, solvents, acids and alkalis. It is firmer and tougher than open-cell foam and recovers from repeated impacts, which suits insulation, packaging and impact-absorbing padding. It cuts, saws, routes, thermoforms and heat-laminates cleanly, so it works for both workshop fabrication and one-off projects.

    Pros
    • Closed-cell PE foam resists water and stays buoyant
    • Good chemical resistance to oils, solvents, acids and alkalis
    • Firmer and tougher than open-cell foam
    • Recovers its shape after repeated impacts
    • Cuts, saws, routes, thermoforms and heat-laminates cleanly
    • Lightweight and odorless
    Cons
    • Less springy and cushioning than open-cell foam
    • LD45 is a soft grade, so it is not a structural material
    • Large sheet size needs space and cutting tools to handle
    • Not a finished part; you shape it yourself

    About the Plastazote LD45 Closed Cell PE Foam Sheet

    Plastazote LD45 is a closed cell, cross-linked polyethylene foam supplied as a sheet. Its structure is a large number of nitrogen cells held within the polyethylene. The foam is lightweight and completely odorless. It does not absorb water, so it is buoyant.

    Because it is polyethylene, the foam resists most oils, solvents, acids and alkalis. Closed cell foams are usually harder, firmer and tougher than open cell foams, and much less springy. Each cell acts like a balloon, so the foam recovers from repeated impacts and returns to its original shape.

    The foam can be thermoformed, sawed, laser cut, routed on CNC machinery and shaped with water jet equipment. It is also easy to split and heat laminate. Common uses include insulation, packaging, impact-absorbing sportswear and casing inserts.

    Questions and answers

    What is LD45 foam?
    LD45 is a low-density grade of Plastazote closed-cell polyethylene foam. It is soft and flexible compared with higher-density PE foams, while keeping the closed-cell water and chemical resistance.
    Can it be cut and shaped at home?
    Yes. The foam can be cut with a knife or saw, routed, laser cut, water-jet cut and thermoformed. Clean edges come more easily with sharp tools or CNC routing.
    Does it absorb water?
    No. The closed cells keep water out, so the sheet stays buoyant and is suitable for wet or outdoor use.
    How does it compare with open-cell foam?
    It is firmer, tougher and less springy than open-cell foam. It resists water and chemicals better but gives less soft cushioning.
    What can I use a 2000 x 1000 mm sheet for?
    Common uses are packaging, case inserts, insulation, impact padding and sports or military-style padding. The large sheet suits cutting multiple pieces from one panel.
    Where is the Plastazote LD45 Closed Cell PE Foam Sheet cheapest?
    At Plastock, for $27.55, as of our latest check.
