Polyethylene Foam Sheet

Polyethylene Foam Sheet

Advanced Seals & Gaskets Ltd is proud to be one of the UK’s leading suppliers of Polyethylene materials. Our large storage facility enables us to stock blocks (‘buns’) of polyethylene in a range of densities and colours, ready for conversion.

Other names sometimes used for this material include block foam, PE foam, polyethylene sponge, or LDPE (low-density polyethylene) foam.

Sheets of Polyethylene foam are split from 2m x 1 m-sized blocks using our state-of-the-art splitting machines, which accurately produce sheets of various thicknesses starting from as little as 1.5mm, supplied in 1m or 2m lengths.

Blocks can also be joined and split into rolls of 10m or more, which can then be cut down into the desired sheet sizes by the customer.

With in-house conversion and lamination services, we can:

  • Split materials down to custom thicknesses

  • Laminate layers to produce non-standard or composite sheets

  • Apply self-adhesives or foil facings.

Our facilities include presses, log cutters, strippers, bandsaws, CNC machines, and coaters, allowing us to produce gaskets, washers, strips, pads, and fabrications from sheets of Polyethylene foam.

    What are Polyethylene Foam Sheets?

    Polyethylene foam is a chemically cross-linked thermoplastic foam with a small, uniform, closed-cell structure. This creates a lightweight, high-quality material with excellent resistance, insulation properties, and a variety of grades, densities, and colours.

    Standard densities include 25kg, 30kg, 45kg, 60kg, and 100kg, as well as grades such as EEV, EVA, conductive, anti-static, and flame-retardant. All are manufactured in 2m x 1m blocks that can be split into sheets or further processed into parts such as strips, sheets, washers, or pads.

    Why use Polyethylene Foam Sheets?

    Polyethylene foams are produced in multiple grades and densities, offering properties suitable for a wide range of applications. Many grades are available in various colours.

    Key properties include:

    • Low compression set

    • Resistance to water, oils, chemicals, and weather

    • Closed-cell structure for tear resistance and prevention of mould or fungus growth

    • High resistance to wear and tear, ozone, and UV

    • Working temperature range: -60°C – +90°C

    • Noise and vibration control

    • Thermal insulation

    Sheets are often preferred when only small quantities are needed, saving money and reducing waste. They are also easier to transport and store.

    Advantages of Using Polyethylene Foam

    Polyethylene foam is versatile, allowing customers to benefit from a range of properties suitable for multiple industries and applications, from dust seals and flame-retardant gaskets to theatre and production props.

    Its closed-cell structure provides effective sealing against liquids, gases, and particles. Additional advantages include:

    • High resistance to wear and tear, ozone, and UV

    • Resilience to repeated impact

    • Wide operating temperature range (-60°C to +90°C)

    • Noise and vibration control

    • Thermal insulation

    Polyethylene foam is aesthetically pleasing, with a smooth texture that is easy to fabricate, laminate, and cut into parts. It is widely used in industries such as:

    • Theatrics and stage production

    • Building and construction

    • HVAC systems

    • Automotive manufacturing

    • Packaging

    • Sports equipment
