Product Information
【Sealing of uneven surfaces】With its flexibility, the foam seals uneven or sharp surfaces to achieve high sealing property.
- Comparison of sealing property with other materials
A material with high sealing property
The sealing property of a sealer such as tape is greatly affected, not only by the properties of the material substance, but also by its close physical contact with the uneven surface of the adherend. A material with high flexibility eliminates gaps with the adherend and realizes high sealing performance.
Sealing property realized by foam
Resin films and fiber materials such as non-woven fabrics may leave small gaps because of their own rigidity (hardness). Sekisui foam is thin, but has excellent flexibility to seal uneven surfaces. It is used for various applications, including sealing (waterproof or dustproof) tape in electronic devices.
