White Sponge Silicone Sheeting
Our White Silicone Sponge Sheeting offers an expanded closed-cell silicone material, designed in a lightweight and versatile form that delivers most of the performance benefits of solid silicone.
White silicone sponge is the perfect choice for industries such as medical, pharmaceuticals, and food processing. The majority of silicone sponge materials in the market are typically based on polydimethylsiloxane (PMDS) derived from silicone gum.
This polymer undergoes a chemical expansion process when heat-cured, resulting in a closed-cell sponge structure. A closed-cell structure means that the cells are non-interconnected, preventing water from wicking through. Silicone sponges are renowned for their excellent mechanical properties and their inherently complete closed-cell structure.
Our White Silicone Sponge Sheeting is an expanded closed-cell material that combines a lightweight and versatile design, offering many of the performance benefits associated with solid silicone.
Key Advantages of Closed Cell White Silicone Sponge:
- Wide Temperature Range: Our silicone sponge can withstand temperatures ranging from -73°C to 200°C. We also offer a high-temperature variant suitable for use up to 270°C; please contact our sales team leader for further information.
- Effective Water Sealing: The closed-cell structure enables efficient water sealing with relatively low compressive forces.
- Compression Set Resistance: Silicone exhibits excellent resistance to compression setting, particularly at higher temperatures compared to most rubber materials. For even better performance, we offer cost-effective low compression set silicone sponges.
- UV and Ozone Resistance: Silicone products are known for their outstanding resistance to UV and ozone, thanks to their inorganic backbone. This provides long-term value.
- Durability: Our silicone sponge sheets are more rugged and durable than most other available materials, ensuring they perform when you need them most.
- Outdoor Gasketing: Given all the advantages mentioned above, silicone sponge is an excellent material choice for outdoor applications, from harsh Arctic conditions to high mountain environments.
We offer a variety of densities, though some may be subject to minimum order quantities. Contact us today to learn more about our White Silicone Sponge Sheeting and how it can benefit your specific industry needs.
