One of the most popular material types available from Advanced Seals & Gaskets Ltd is Polyethylene, available in numerous grades, densities and colours, which can be supplied as a range of products including cut sheets. One such type is Expanded Cross Linked Closed Cell Polyethylene, which is also sold under the trade names Alveolit® or Alveo, which is used to manufacture alveo sheets.
This physically cross-linked, closed-cell polyethylene foam is produced in densities of 33kg, 67kg and 100kg in continuous roll lengths in thicknesses between 2mm to 10mm, however, as we carry out all our conversion on-site, we can cut these down into sheets 1 meter wide by 1 meter or 2 meters long or into smaller or larger bespoke alveo sheets and pads, we can also use state of the art splitting machinery to split sheets of Alveo down or laminate layers together so that we can offer countless non-standard thicknesses to order.
Alveo sheets can be supplied either plain or laminated with a choice of one of our many self-adhesives, foils or other materials.
What are Alveo Sheets?
Alveo is a physically crosslinked, closed-cell polyolefin (a family of polyethylene and polypropylene thermoplastics) foam produced in continuous rolls in a three-stage process: extrusion, crosslinking, and vertical foaming produced by the process of polymerisation of ethylene and propylene using oil and natural gas.
Alveo polyethylene is manufactured in a range of densities, in black (anthracite) or white colour options and with the advantage of being easily split or laminated in order for us to offer non-standard thicknesses. Alveo is manufactured in continuous lengths of material, in roll lengths of up to 75 to 100 meters depending on the material thickness, which can be cut down and supplied as alveo sheets or pads of bespoke sizes.

Why use Alveo Sheet?
Alevo polyethylene foam is manufactured with a fine regular closed-cell structure that is soft and flexible, with skin on both faces. It is manufactured in a range of standard thicknesses, but can easily be split or laminated to create non-standard thickness, and converted into a range of products including alveo sheets. Alveo polyethylene foam offers low water absorption, and excellent vapour permeability with good chemical, ozone and UV resistance.
It’s an odourless material, offering a wide operating temperature range which can also be manufactured and supplied in a flame retardant grade. Alveo sheets are often taken for covering large surfaces or to cut lengths of sealing strips or pads for use with sealing against dust, air and moisture, gap-filling between uneven surfaces or for reducing unwanted noise and vibration.
This soft compressible foam creates an excellent seal as its closed-cell and easy to compress, which is essential for an effective gasket where they are needed to fill deformities and gaps. Alveo rolls can be taken in full by customers giving them the freedom to cut their own alveo sheets and parts out for use or resale as and when they’re required.
Advantages of using Alveo Sheets
Using Alveo polyethylene sheets offer countless advantages, the material is highly durable and resistant, inert to many chemicals, weather-resistant and has excellent insulation properties and a wide operating temperature range of -80°C to +100°C.
These qualities make Alveo highly desirable in a variety of applications such as padding, protection and cushioning with automotive, construction and manufacturing.
Alevo polyethylene is manufactured in continuous rolls, in a range of roll widths and thicknesses, however, the material can be easily converted into a range of converted parts such as alveo sheets, pads and sealing strips or taken in full rolls, giving customers the freedom to cut their own parts as required.
Benefits of Using Alveo Polyethylene Foam
- Closed-cell and cross-linked structure makes the material impermeable to air and water
- Good temperature resistance.
- Lightweight and durable.
- Inert to many chemicals
- Good weather resistance
