Polyethylene Foam FAQs.

What is Polyethylene Foam?

Polyethylene foam is a closed-cell foam made from thermoplastic material. It offers strong resistance to chemicals, grease, and water.

Our polyethylene foam is supplied in sheets, rolls, and strips. It is also available in a variety of colours to suit a range of applications.

What is Crosslinked Polyethylene Foam?

Crosslinked polyethylene foam, also known as XLPE, is a denser and smoother variation of standard polyethylene foam. It undergoes a chemical or physical crosslinking process, which improves its durability and tensile strength.

At AS Rubber, this type of foam is offered in different densities (ranging from 25 Kg/m3 to 45 Kg/m3) and colours, making it suitable for many applications.

What is Polyethylene Foam Used For?

Polyethylene foam has many practical applications due to its lightweight, cushioning, and water-resistant nature. It is regularly used in:

  • Protective packaging
  • Thermal insulation
  • Soundproofing
  • Automotive components for vibration control
  • Sports and leisure items such as mats and padding

Is Polyethylene Foam Waterproof?

Yes, polyethylene foam is waterproof. Its closed-cell construction prevents the absorption of water, which makes it well-suited for use in damp or wet environments. This also helps it retain its insulating and cushioning qualities over time, even when moisture is present.
