Silicone Sponge Sheet Silicone Sponge Sheet
Silicone Sponge Sheet – Versatile Application
Our expanded closed-cell silicone sponge sheeting combines the exceptional performance advantages of solid silicone with a softer, more compliant texture. We offer silicone sponge sheets and strips in various sizes, densities, colors, and can provide self-adhesive backing upon request.
Our standard thickness is an off-white sheet with a density of 17 kg/m3.
Key Advantages of Closed-Cell Silicone Sponge
- Wide Temperature Range: Silicone sponge is capable of withstanding temperatures from -60°C to 260°C.
- Effective Water Sealing: The closed-cell structure ensures excellent water sealing with minimal compressive forces.
- Compression Resistance: Silicone demonstrates outstanding compression set resistance, particularly at elevated temperatures, surpassing most rubber materials. We even offer low compression set silicone sponges for superior performance.
- UV and Ozone Resistance: Silicone products exhibit exceptional resistance to UV and ozone, owing to their organic composition, ensuring long-term durability.
- Durability: In situations where durability is a must, silicone sponge components outshine many other available alternatives.
- Outdoor Gasketing: Considering all these benefits, silicone sponge stands as an excellent choice for outdoor environments, spanning from arctic to desert conditions.
Most commercially available silicone sponge products are crafted from heat-cured gum-based polydimethylsiloxane (PMDS). This polymer expands chemically during curing, forming the closed-cell sponge structure. The non-interconnecting cells of closed-cell silicone sponge prevent water from permeating through.
In summary, silicone sponges boast superior mechanical properties and deliver many of the performance advantages of solid silicone, all in a more pliable and adaptable form.
