Description
Our White Expanded Silicone Foam Strip with Self-Adhesive Backing is a flexible, durable sealing and cushioning material designed for a wide range of industrial, commercial and general-purpose applications.
Manufactured from high-quality expanded silicone sponge, this strip combines the excellent performance characteristics of silicone rubber with a soft, compressible foam structure. The self-adhesive backing provides quick and convenient installation, helping the strip remain securely positioned during application.
With an operating temperature range of approximately -60°C to +200°C, silicone foam strip is particularly suitable for applications exposed to high temperatures, UV light, ozone, oxidation and changing weather conditions.

Additional Technical Notes
Density values can vary depending on the dimensions and thickness of the finished strip.
Hardness measurements are based on thicker material samples. On thinner sections, the measured hardness may increase as a result of changes in material density.
Compression characteristics can also vary according to the thickness and density of the strip. Thinner material may require greater compressive force.
Why Choose Self-Adhesive Silicone Foam Strip?
Expanded silicone foam provides an effective combination of temperature resistance, flexibility, compression and environmental durability. Unlike standard solid silicone rubber, its sponge structure allows the material to compress easily, making it particularly useful where an adaptable seal is required around uneven surfaces or variable gaps.
The integrated adhesive backing also simplifies installation by eliminating the need for separate adhesive in many applications.
