What are Polyethylene Foam Gaskets?

Gaskets are a cut shaped piece of material, sometimes in the form of a pad, washer or strip which is placed between two surfaces to create a seal, provide cushioning or insulation. Polyethene foam gaskets are manufactured from a high quality, lightweight closed-cell material. Polyethene is a great material for using gaskets as it is flexible, has a number of resistances and insulation properties as well as being available in a variety of grades, densities, colours.

Why use Polyethylene Foam gaskets

Polyethylene foam gaskets come in a range of grades and densities offering a range of properties for different applications. Polyethylene foam gaskets have a low compression set, resistance to water, oils, chemicals and weather as well as being excellent thermal insulation material. Being a closed-cell material, it has good tear resistance and doesn’t support mold or fungus growth. Different variants of polyethene include FDA grades for use with food, beverage and pharmaceutical applications, Flame Retardant and anti-static.

Different Grades

Having a network of manufacturers and suppliers, allows ASG to offer a full range of polyethylene types, densities and colours, many of which are readily available from stock for a quick turnaround.  Below is just a selection of some of our popular polyethylene materials used for gasket production:

  • Alveo
  • Anti-static
  • Ethafoam
  • Eva foam
  • Flame retardant
  • Chemically cross-linked 
  • Plastazote
  • Stratocell

Benefits of Polyethylene Foam Gaskets

Using polyethylene foam gaskets offers a huge number of benefits, it’s a non-toxic, high quality, lightweight material, which has good water, ozone, UV, weathering, grease and chemical resistance. Polyethylene has a wide operating temperature range, with higher temperature and flame retardant variants also available. Due to the number of grades on offer, polyethylene foam gaskets can be found in most applications where weather-resistant, acoustic and thermal insulation and tight sealing is required.
