Description
Our White Expanded Silicone Sponge Rubber Strip is a flexible, lightweight sealing and cushioning material suitable for demanding industrial and commercial applications. Supplied in a 5-metre roll, it is available in a range of widths and thicknesses to suit different requirements.
The closed-cell silicone sponge construction provides reliable performance across a wide temperature range of -60°C to +200°C. It also offers excellent resistance to ozone, oxidation, ultraviolet light and general weathering, making it suitable for both indoor and outdoor environments.
This versatile silicone strip can be used for sealing, insulation, cushioning, vibration reduction, gap filling and protection between components. Its white finish makes it particularly suitable for clean, visible or hygiene-sensitive applications.

Technical Notes
* Density was measured using a 25mm-diameter cord sample. The density of other sizes may differ from the stated value.
** Hardness was measured using a 10mm-thick sample. Measurements taken from material thinner than 10mm may produce a higher hardness reading.
*** Compression measurements were taken using a 25mm-thick sample. Compressive stress may increase as the thickness and density of the material change.
Please select the required width and thickness from the available options. Contact us if you require a size that is not currently listed.
