Alveo Foam Strip

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 strips. One such type is Expanded Cross Linked  Closed Cell Polyethylene, which is also sold under the trade names Alveolit® or Alveo.   

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 from which strips can be cut.  By following our customers' samples, drawings or given dimensions, we can produce made to measure Alveo Foam strips using our bandsaws, strippers, log cutters and even presses depending upon the size and quantity of strips required. 

In-house production allows us to closely oversee the whole production process to ensure that we consistently produce high quality, competitive prices strips. Our Alveo Foam strips are cut from sheets or rolls of material, which can be split down to thicknesses starting at just 1.5mm thick, we can produce strips from 4mm in width and from a few millimetres long up to 75 meters in length (depending on thickness). 

During the conversion process, we can laminate layers of Alveo Foam material to produce greater depths, supply them plainly, laminated with a choice of self-adhesive foils or even other materials.

What are Alveo Foam Strips?

Alveo is a physically crosslinked, closed-cell polyolefin (a family of polyethylene and polypropylene thermoplastics)  foam produced in continuous sheets 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 Foam strips are lengths of material either cut to a specific length or supplied as continuous rolls and coils to be cut down as and when they’re needed by the end-user. 

Alveo Foam strips are often purchased to be used in the same way as a gasket, whereby they are used to create a seal between uneven surfaces and fill irregularities or for anti-vibration and acoustic insulations.

    Why use Alveo Foam Strips?

    Alevo polyethylene foam is manufactured in roll form, the material has a fine regular close 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 gaskets.  

    Alveo polyethylene foam offers low water absorption, 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 Foam strips are often used in the same way as gaskets, to fill gaps and irregularities between two surfaces and to 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.

    In order for strips to work effectively, it needs to compress and fill the entire space to create pressure and an airtight protective seal.

    Advantages of using Alveo Strips

    Using Alveo polyethylene strips 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 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.
    • Odourless
