Flame Retardant Plastazote (LD45FR) Polyethylene Foam

By working with a multitude of reputable material manufacturers and suppliers, Advanced Seals & Gaskets Ltd are able to offer a range of Polyethylene materials in many grades and densities, one of which includes Plastazote foam in a Flame Retardant (flame retardant plastazote) 45kg density or LD45FR as it is more commonly referred to.

This material is a closed cell, cross-linked polyethylene foam which is incredibly lightweight, and free from chemical agents which enables customers to use this material in highly sensitive environments where flame and heat resistance are crucial. LD45FR Plastazote PE foam is manufactured and stocked in block form from which we can split sheets or rolls of material in various thicknesses starting at just 1.5mm, as we offer in-house conversion and lamination services, we can not only split materials down, we can also laminate layers together and apply self adhesives or foil facings.

Our vast onsite conversion facilities houses a number of presses, log cutters, strippers, bandsaws and CNC machines from which we can produce a number of LD45FR products including gaskets, washers, strips, pads and fabrications.

    What Is Flame Retardant Plastazote (LD45FR) Polyethylene Foam?

    Flame Retardant Plastazote LD24FR foam is a type of cross-linked, closed cell polyethylene foam, man- made using crude oil into which nitrogen is blown and the foam is expanded.

    This manufacturing process produces a tough and flexible material which is manufactured using the same compound as standard LD24, but with the addition of flame retardant additives. When the plastazote foam is compressed each nitrogen filled cell acts like a balloon, causing the foam to bounce back to its original shape.

    Being a closed cell structure of plastazote means it is impenetrable to air and moisture and will not allow liquids to pass through or be absorbed. Plastazote like other polyethylene foams are manufactured in a range of densities for us in different applications. The density of the foam is measured as the weight or mass of the foam across its entire volume or within a cubic meter (m3). The denser the foam, the heavier and more compact the material is, this can have an effect on some of the properties of the material and how it performs.

    Why Use Flame Retardant Plastazote (LD24FR) Polyethylene Foam?

    LD24FR Plastazote foam offers all of the features of LD24, but is formulated with flame retardant additives mixed into the compound, often used as an alternative to more expensive, less inert materials such as EPDM or Neoprene sponge.

    LD24FR Plastazote foam is a low density foam which can be easily split, cut and shaped. It offers excellent recovery following compression and impact and a good resistance to a range of chemicals, solvents, acids, alkalies and some oils, meaning it can be utilised in many applications. All Plastazote materialis, including LD24FR are lightweight and free from chemical agents, therefore used in many ‘clean’ applications such as food, pharmaceutical and science.

    LD24FR offers great thermal properties and offers high levels of vibration, shock absorption, heat and flame resistance for use as protective packaging or for cutting into gaskets and other seals for use within the automotive, construction and aviation industries.

    Advantages Of Using Flame Retardant Plastazote (LD24FR) Polyethylene Foam

    Using Flame Retardant Plastazote LD24FR foam offers countless advantages and is highly utilised in numerous industries and applications, Plastazote foam is a man-made material, designed to suit a range of requirements and is available in a choice of grades, densities and colours to suit.

    LD24FR is odourless, lightweight, buoyant, non-toxic and offers resistance to many oils, solvents, acids, alkalis heat and flame. It’s closed cell surface does not allow the absorption of liquids and is easy to keep clean, as well as being weatherproof and UV stable.

    Plastazote foams are usually the preferred choice for protective packaging such as case inserts, the material has excellent recovery from repetitive impact and is highly energy absorbent, which also gives it good thermal insulation properties.

    Using these materials for packaging and transporting goods offers customers cost saving benefits as there is a reduction in damage to products whilst in transit or storage.

    Typical Applications for Flame Retardant Plastazote (LD24FR) Polyethylene Foam

    LD24FR Flame Retardant Plastazote polyethylene foam is most commonly found used in packaging applications, being low density LD24FR can be easily cut and manipulated to fit around delicate or fragile products. Other applications can include:

    • Making costumes or props
    • Displays
    • Used in the manufacture of sports equipment
    • Water repellent and buoyant for use as floatation or buoyancy aids
    • Used for surface protection and components for medical and healthcare applications
    • Transport and Automotive trims and gaskets
    • Electronics packaging
