Sheets of Polyethylene are one the most popular products supplied by Advanced Seals & Gaskets Ltd, available in a number of grades and densities,  including Ethafoam Sheets which are just one of various types of Polyethylene Foams we stock.  

Our materials are sourced from the highest quality manufacturers from across the world, allowing us to offer our customers more choice when they are looking for sealing, insulation and packaging solutions to their application.  Most polyethylene materials are manufactured in block form, this includes Ethafoam, which vary in size depending on the density and grade but as standard are supplied in 2m x 1m or 1m x 1m sized sheets, in standard thicknesses from 5mm up to 50mm.

However stock materials can be split down into other thicknesses starting from around 1.5mm, however these sheets will have a skin / cell finish.   As we also offer an in-house adhesive and lamination service, we can not only split Ethafoam sheet down, we can also glue sheets together to create very thick products, or laminate layers of different materials producing composite sheets and apply self adhesives or foil facings.  


  • Packaging and Shipping: Ethafoam Sheets are essential for protecting fragile items during transport and shipping, providing cushioning to prevent damage.
  • Electronics and Equipment: These sheets are used in the electronics industry to provide cushioning and protection for sensitive components during storage and handling.
  • Automotive Manufacturing: Ethafoam Sheets play a role in the automotive industry, providing cushioning and protection for parts and components during storage, transport, and assembly.
  • Marine and Aerospace: These sheets are valuable in marine and aerospace applications, providing buoyancy and cushioning for equipment and components.
  • Sporting Goods: Ethafoam Sheets find application in sporting goods like helmets, padding, and protective gear, providing impact absorption and protection.

At Advanced Seals and Gaskets, we prioritize innovation and performance in our Ethafoam Sheets. Their cushioning, buoyancy, and sealing capabilities make them invaluable in various industries where protection and reliability are paramount. Choose Advanced Seals and Gaskets' Ethafoam Sheets to elevate your industrial processes with top-tier sealing and cushioning solutions that offer exceptional durability and reliability.

    What are Ethafoam Sheets?

    Ethafoam sheets are produced by splitting down master blocks of material into pre-measured thicknesses ranging from as little of 1.5m.  The Material itself is manufactured in sheet or plank form in thicknesses up to 50mm, but greater depths can be achieved by laminating multiple sheets together. 

    These sheets can either be further converted here at ASG into other components such as strips, pads, gaskets or washers or alternatively shipped to the customer in full who will carry out their own conversions.  Ethafoam sheets are a resilient and flexible closed-cell polyethylene foam, similar to polystyrene in appearance and feel, which has a range of uses due to its durability and flexibility. 

    Ethafoam is a low-density plastic foam made by expanding polyethylene by around 30 times in volume, which is manufactured or ‘extruded’ as planks so that it has skin on both faces which is textured, with exposed cell along the edges where it has been down to size. 

    Ethafoam sheets are available in white or grey, and in different grades and densities such as 24kg/m2 and 64kg/m2 for packaging, 102kg/m2 and 145kg/m2 for high load bearing,  a Flame Retardant grade and Anti-static which is recognisable by its pink colouration.  Ethafoam sheets and components cut from them are usually found for use as packaging or transportation due to its impact, shock absorption and cushioning properties and its resistance to moisture.


    Why use Ethafoam Foam Sheet?

    Ethafoam sheets are recognisable by their finishe and texture, in comparison to some the PE foams they are very rigid and plastic like.  Sheets of Ethafoam are held in stock ready for shipping direct to customers, or converted into one of our many other bespoke products to order where they are often used as packaging, sealing, provide cushioning and vibration absorption or as heat insulation. 

    Ethafoam sheets are often found used within packaging such as case or container linings and are vital in the storage and transportation of fragile, sensitive and valuable products where protection from repeated impact, moisture, chemicals and mildew or fungus is required, Ethafoam is a go to material, as the sheets are easily machined or fabricated into bespoke sized products in order to securely hold items in place whilst providing cushioning. 

    As Ethafoam is manufactured in a number of grades and densities, the sheets can be used for holding products regardless of its weight, however due to the coarse nature of the material it may not always be suitable for direct contact with products especially those with a polished or delicate surface as it may cause abrasive damage.

    Benefits of using Ethafoam Polyethylene:

    • Shock, impact and vibration absorption
    • Moisture resistant
    • Impervious to many chemicals, mould, fungus and bacteria
    • Easy to cut, carve and fabricate
    • Available in a range of densities
    • Lightweight

    Alternative packaging foams

    • Convoluted or Eggbox Polyurethane
    • Pick & pluck Polyurethane
    • Anti-static Polyethylene
    • Anti-static Polyurethane
    • Conductive Polyethylene
    • Plastazote foams
    • Static Dissipative Polyethylene Foam

    Advantages of using Ethafoam Sheets

    Ethafoam materials are manufactured  in sheet or ‘plank’ form as standard, but as this material is so machinable, it can easily be pressed and sawn into smaller products including pads, strips and washers, or even joined together to produce continuous lengths or rolls of material.  

    Ethafoam Polyethylene is a very strong, lightweight material with the sheets having a skin finish which creates a moisture, mildew and bacteria resistant strip.  This material itself is resilient therefore the sheets are able to withstand repeated impact, vibration and will insulate against high and low temperatures - offering a working temperature range of -30 to +80ºC and resistance to many chemicals. 

    Just some of the advantages of using Ethafoam sheets is its durability, choice of grey or white colours, selection of available densities from 24kg/m3 to 145kg/m2 to be able to withstand even extreme weight and the availability of specialist grades such as Flame Retardant and Anti-Static.  Ethafoam shock and vibration absorption levels can be increased by stacking or layering multiple sheets together to create depth.  

    Due to the choice of Ethafoam materials available, the sheets can be found used in a range of applications from standard packaging around electrical appliances, white goods and case inserts through to supporting very heavy objects such as ground cables or under machinery feet.
