Scope of application for closed-cell foams
With its closed-cell foams, Sekisui Alveo offers the right solution for a wide variety of industries. Each foam has its own, individually tailored properties with which it can meet the challenges of specific areas of application. These include, for example, the shoe industry, orthopedics and medical industry, transport, packaging, the processing industry, sealing, and insulation as well as construction and installation. In addition, Sekisui Alveo is constantly developing new products in order to continue finding new applications.
What are the benefits of cutting closed-cell with CO2-lasers?
- Clean and filigree cut edges without post-processing
- No tool wear due to the non-contact cutting process
- High flexibility in the choice of contour
- Engraving of the surface possible in one step
- No material distortion as with conventional processing methods
- Precise cutting without overcuts
- No drying process required after processing
- Cost-reduction - No further work steps prior to further processing

What is a closed-cell foam?
Closed-cell is the name for foams in which the cell walls of the individual vacuoles are completely closed. In contrast, there are open-cell foams in which the cell structure is open and which therefore absorb liquids and are air-permeable. Closed-cell foams are largely waterproof and airtight. The result is a firmer and more stable foam with other areas of application. The spring effect is also lower here. The cell structure of the foam does not affect its thickness. When choosing a suitable foam, attention should always be paid to the properties required in order to find a suitable solution. The Sekisui Alveo range includes a large number of different foams for every area of application.
Properties of closed-cell foam:
- Powerful insulator, good thermic insolation property
- Air tight seal
- Moisture barrier
- Long life span with good weather resistance
- Good tear resistance
- Varying degrees of hardness while lighter than solids
- ecologically and chemically neutral
- Uniform structure
