Polyethylene Foam Seals
Polyethylene Foam Seals
Foam seals can take the form of gaskets, washers, strips and other extruded profiles, which can be manufactured by ASG using one of many materials sourced from a network of worldwide suppliers, which are recognised as one of the UK’s leading convertors and suppliers of Polyethylene products, including polyethylene foam seals.
Our site not only houses state of the art conversion and laminating machinery, but we also have extensive storage facilities enabling us to stock blocks (buns), rolls and sheets of polyethylene, in a range of densities and colours all ready to be converted into one of 1000’s of products including multiple seal types.
Other terms and names often used to describe this material are block foam, PE foam, polyethylene sponge or LDPE (low density Polyethylene) foam. Blocks of Polyethylene foam can be split down to thicknesses starting from as little as 1.5mm, in 2 metre x 1 metre sized sheets or rolls - made by joining blocks of material together prior to splitting them, both of which can be used to further convert into polyethylene foam seals.
Polyethylene foam seals can be cut or pressed from rolls or sheet of material, or alternatively extruded into certain profiles which are all designed for the purpose of preventing leaks or the ingress of air, fluids and gas. All our polyethylene foam seals are made to order and are produced by following samples or drawings provided by customers to ensure the final product perfectly fits the application.
As each form of polyethylene foam seal needs to be manufactured using a different process, ASG have invested heavily in various machinery allowing us to offer seals in both high and low volumes at competitive prices

What Are Polyethylene Foam Seals?
Polyethylene foam seals are devices that are used to join surfaces together, acting as a separator or a barrier to prevent liquids, particles or gases escaping or penetrating the application. ‘Seal’ is a generic term for a group of products often taking the form of cut gaskets, strips, washers, extruded or moulded profiles and edge trims.
The Polyethylene foam used in the production of these seals is a chemically cross-linked foam, part of the Thermoplastic foam family, which is foamed prior to curing to create small, uniform, closed-cell structure and a high quality, lightweight material. Polyethylene materials demonstrate a number of resistances and insulation properties as well as being available in a variety of grades such as EEV, EVA, Conduction, Anti-static and Flame Retardant.
Densities in which Polyethylene foam seals can be produced include 25kg, 30kg, 45kg, 60kg, 100kg densities- 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 vary some of the properties of the material and how it performs.
Why Use Polyethylene Foam Seals?
Polyethylene foams are quite popular and therefore are often available from stock, customers choose Polyethylene foam for their seal production as the material is in choice of grades allowings the seals to be safely used in different applications and environments. Polyethylene foam seals regardless of the grade used have the same following set of properties - a low compression set, are resistant to water, oils, chemicals and weather, with additives added to produce other grades and thus additional properties.
Being made from a closed cell material, these seals have a good tear resistance making them easy to accurately convert even using the most vigorous processes, its smooth surface also mean these foams don't support mold or fungus growth. Polyethylene foam and seals made from this material have a number of desirable properties including resistance to wear and tear, Ozone, UV and a working temperature range of -60°C - +90°C. Polyethylene foam also offers excellent mechanical characteristics including noise and vibration control and can be used for thermal insulation.
Polyethylene foam seals can be used to fill gaps and irregularities between uneven surfaces and fixtures, provide a solution to unwanted rattles, noise, vibrations, to seal against air, gas, dust and liquids, and can also be used to cushion between moving parts to reduce friction and damage to components and equipment and also as edge trims or surface protection.
Types of Polyethylene Available

Advantages Of Using Polyethylene Foam Seals
One of the most popular materials supplied by ASG is Polyethylene, which is wide used in the production of seals as it is made in a choice of grades and densities giving customers the benefit of having a number of advantages, and a choice of properties allowing the material to be utilised in numerous industries and applications from dust seals to flame retardant washers.
Polyethylene foam is a man-made material, with a closed cell structure which can be used in sealing applications against liquid, gases and particles, it has a high resistance to wear and tear, Ozone, UV, resilience to repeated impact and a working temperature range of -60°C to +90°C. It also offers excellent mechanical characteristics including noise and vibration control, shock absorption and can be used for thermal insulation.
Polyethylene foams are aesthetically pleasing, with a nice texture which are easy to fabricate, laminate and cut into parts using a range of techniques and processes for use within the theatrics, building and construction, HVAC, automotive, packaging and sports industries.
Benefits Of Using Polyethylene Foam
- Lightweight, strong & durable
- Good impact and shock absorbing properties
- Water repellent and buoyant
- Excellent chemical, solvent, grease and fluid resistance
- Good thermal and acoustic insulation
- Easy to cut, convert & shape
